Arch Linux Security Advisory ASA-201908-19 ========================================== Severity: Critical Date : 2019-08-28 CVE-ID : CVE-2019-11500 Package : pigeonhole Type : arbitrary code execution Remote : Yes Link : https://security.archlinux.org/AVG-1027 Summary ======= The package pigeonhole before version 0.5.7.2-1 is vulnerable to arbitrary code execution. Resolution ========== Upgrade to 0.5.7.2-1. # pacman -Syu "pigeonhole>=0.5.7.2-1" The problem has been fixed upstream in version 0.5.7.2. Workaround ========== None. Description =========== IMAP and ManageSieve protocol parsers in Dovecot before 2.3.7.2 and Pigeonhole before 0.5.7.2 do not properly handle NUL byte when scanning data in quoted strings, leading to out of bounds heap memory writes. Impact ====== A remote, unauthenticated attacker can access sensitive information or execute arbitrary code on the affected host via a crafted ManageSieve command.

Arch Linux Security Advisory ASA-201908-17 ========================================== Severity: Medium Date : 2019-08-27 CVE-ID : CVE-2019-9511 CVE-2019-9513 Package : libnghttp2 Type : denial of service Remote : Yes Link : https://security.archlinux.org/AVG-1024 Summary ======= The package libnghttp2 before version 1.39.2-1 is vulnerable to denial of service. Resolution ========== Upgrade to 1.39.2-1. # pacman -Syu "libnghttp2>=1.39.2-1" The problems have been fixed upstream in version 1.39.2. Workaround ========== None. Description =========== - CVE-2019-9511 (denial of service) An issue has been found in several HTTP/2 implementations, where the attacker requests a large amount of data from a specified resource over multiple streams. They manipulate window size and stream priority to force the server to queue the data in 1-byte chunks. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both, potentially leading to a denial of service. - CVE-2019-9513 (denial of service) An issue has been found in several HTTP/2 implementations, where the attacker creates multiple request streams and continually shuffles the priority of the streams in a way that causes substantial churn to the priority tree. This can consume excess CPU, potentially leading to a denial of service. Impact ====== A remote attacker is able to cause a denial of service by sending a specially crafted packet.

Resolution ========== Upgrade to 2:1.12.8-1. # pacman -Syu "go-pie>=2:1.12.8-1" The problems have been fixed upstream in version 1.12.8. Workaround ========== None. Description =========== - CVE-2019-9512 (denial of service) An issue has been found in several HTTP/2 implementations, where the attacker sends continual pings to an HTTP/2 peer, causing the peer to build an internal queue of responses. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both, potentially leading to a denial of service. - CVE-2019-9514 (denial of service) An issue has been found in several HTTP/2 implementations, where the attacker opens a number of streams and sends an invalid request over each stream that should solicit a stream of RST_STREAM frames from the peer. Depending on how the peer queues the RST_STREAM frames, this can consume excess memory, CPU, or both, potentially leading to a denial of service. - CVE-2019-14809 (insufficient validation) An issue has been found in Go before 1.12.8, where url.Parse would accept URLs with malformed hosts, such that the Host field could have arbitrary suffixes that would appear in neither Hostname() nor Port(), allowing authorization bypasses in certain applications. Note that URLs with invalid, not numeric ports will now return an error from url.Parse. Impact ====== A remote attacker is able to cause a denial of service by sending a specially crafted packet or bypass authorization due to insufficient validation.

Description =========== - CVE-2018-11782 (denial of service) Subversion svn:// connections, including svn+ssh:// and svn+<custom>://, use a custom network protocol [1] with Lisp-like syntax. The code implementing the protocol has dedicated codepaths for serialization of revision numbers into protocol integers. A particular client query could cause the server to attempt to reply with a revision number whose value is the invalid revision number constant `SVN_INVALID_REVNUM`, thereby triggering an assertion failure in the the serialization layer. - CVE-2019-0203 (denial of service) A null-pointer-dereference has been found in svnserve that results in a remote unauthenticated Denial-of-Service in some server configurations. The vulnerability can be triggered by an unauthenticated user if the server is configured with anonymous access enabled. Impact ====== A remote attacker is able to cause a denial of service by sending a special packet.

Arch Linux Security Advisory ASA-201908-9 ========================================= Severity: High Date : 2019-08-16 CVE-ID : CVE-2019-9848 CVE-2019-9849 Package : libreoffice-still Type : multiple issues Remote : Yes Link : https://security.archlinux.org/AVG-1010 Summary ======= The package libreoffice-still before version 6.2.6-1 is vulnerable to multiple issues including arbitrary command execution and information disclosure. Resolution ========== Upgrade to 6.2.6-1. # pacman -Syu "libreoffice-still>=6.2.6-1" The problems have been fixed upstream in version 6.2.6. Workaround ========== None. Description =========== - CVE-2019-9848 (arbitrary command execution) An issue has been found in LibreOffice before 6.2.5, where documents can specify that pre-installed scripts can be executed on various document events such as mouse-over, etc. LibreOffice is typically also bundled with LibreLogo, a programmable turtle vector graphics script, which can be manipulated into executing arbitrary python commands. By using the document event feature to trigger LibreLogo to execute python contained within a document a malicious document could be constructed which would execute arbitrary python commands silently without warning. In the fixed versions, LibreLogo cannot be called from a document event handler. - CVE-2019-9849 (information disclosure) LibreOffice has a 'stealth mode' in which only documents from locations deemed 'trusted' are allowed to retrieve remote resources. This mode is not the default mode, but can be enabled by users who want to disable LibreOffice's ability to include remote resources within a document. A flaw existed where bullet graphics were omitted from this protection prior to version 6.2.5. Impact ====== A remote attacker is able to execute arbitrary commands via a specially crafted document or disclose bullet graphics from locations which should be hidden when 'stealth mode' is enabled.

Arch Linux Security Advisory ASA-201908-8 ========================================= Severity: Medium Date : 2019-08-10 CVE-ID : CVE-2019-10208 CVE-2019-10209 Package : postgresql Type : multiple issues Remote : Yes Link : https://security.archlinux.org/AVG-1019 Summary ======= The package postgresql before version 11.5-1 is vulnerable to multiple issues including access restriction bypass and information disclosure. Resolution ========== Upgrade to 11.5-1. # pacman -Syu "postgresql>=11.5-1" The problems have been fixed upstream in version 11.5. Workaround ========== None. Description =========== - CVE-2019-10208 (access restriction bypass) A security issue has been found in PostgreSQL < 11.5 where given a suitable SECURITY DEFINER function, an attacker can execute arbitrary SQL under the identity of the function owner. An attack requires EXECUTE permission on the function, which must itself contain a function call having inexact argument type match. For example, length('foo'::varchar) and length('foo') are inexact, while length('foo'::text) is exact. As part of exploiting this vulnerability, the attacker uses CREATE DOMAIN to create a type in a pg_temp schema. The attack pattern and fix are similar to that for CVE-2007-2138. - CVE-2019-10209 (information disclosure) An issue has been found in PostgreSQL >= 11.0 and < 11.5. In a database containing hypothetical, user-defined hash equality operators, an attacker could read arbitrary bytes of server memory. For an attack to become possible, a superuser would need to create unusual operators. It is possible for operators not purpose-crafted for attack to have the properties that enable an attack, but we are not aware of specific examples. Impact ====== An authenticated attacker can read arbitrary bytes of server memory or execute arbitrary SQL commands under a different identity than its own.

Arch Linux Security Advisory ASA-201908-4 ========================================= Severity: Critical Date : 2019-08-05 CVE-ID : CVE-2019-13917 Package : exim Type : arbitrary code execution Remote : Yes Link : https://security.archlinux.org/AVG-1011 Summary ======= The package exim before version 4.92.1-1 is vulnerable to arbitrary code execution. Resolution ========== Upgrade to 4.92.1-1. # pacman -Syu "exim>=4.92.1-1" The problem has been fixed upstream in version 4.92.1. Workaround ========== None. Description =========== Exim 4.85 through 4.92 (fixed in 4.92.1) allows remote code execution as root in some unusual configurations that use the ${sort } expansion for items that can be controlled by an attacker (e.g., $local_part or $domain). Impact ====== A remote attacker can, in some unusual configurations, execute arbitrary code via a crafted e-mail.

Arch Linux Security Advisory ASA-201908-3 ========================================= Severity: Medium Date : 2019-08-05 CVE-ID : CVE-2019-14232 CVE-2019-14233 CVE-2019-14234 CVE-2019-14235 Package : python2-django Type : multiple issues Remote : Yes Link : https://security.archlinux.org/AVG-1014 Summary ======= The package python2-django before version 1.11.23-1 is vulnerable to multiple issues including denial of service and sql injection. Resolution ========== Upgrade to 1.11.23-1. # pacman -Syu "python2-django>=1.11.23-1" The problems have been fixed upstream in version 1.11.23. Workaround ========== None. Description =========== - CVE-2019-14232 (denial of service) If ``django.utils.text.Truncator``'s ``chars()`` and ``words()`` methods were passed the ``html=True`` argument, they were extremely slow to evaluate certain inputs due to a catastrophic backtracking vulnerability in a regular expression. The ``chars()`` and ``words()`` methods are used to implement the ``truncatechars_html`` and ``truncatewords_html`` template filters, which were thus vulnerable. The regular expressions used by ``Truncator`` have been simplified in order to avoid potential backtracking issues. As a consequence, trailing punctuation may now at times be included in the truncated output. - CVE-2019-14233 (denial of service) Due to the behavior of the underlying HTMLParser, django.utils.html.strip_tags() would be extremely slow to evaluate certain inputs containing large sequences of nested incomplete HTML entities. The strip_tags() method is used to implement the corresponding striptags template filter, which was thus also vulnerable. strip_tags() now avoids recursive calls to HTMLParser when progress removing tags, but necessarily incomplete HTML entities, stops being made - CVE-2019-14234 (sql injection) Key and index lookups for JSONField and key lookups for HStoreField were subject to SQL injection, using a suitably crafted dictionary, with dictionary expansion, as the **kwargs passed to QuerySet.filter(). - CVE-2019-14235 (denial of service) If passed certain inputs, django.utils.encoding.uri_to_iri() could lead to significant memory usage due to excessive recursion when re-percent encoding invalid UTF-8 octet sequences. Impact ====== A remote attacker can cause a denial of service via crafted content, or alter the database via a SQL injection.
