Arch Linux Security Advisory ASA-202104-10 ========================================== Severity: High Date : 2021-04-29 CVE-ID : CVE-2021-25214 CVE-2021-25215 CVE-2021-25216 Package : bind Type : multiple issues Remote : Yes Link : https://security.archlinux.org/AVG-1890 Summary ======= The package bind before version 9.16.15-1 is vulnerable to multiple issues including arbitrary code execution and denial of service. Resolution ========== Upgrade to 9.16.15-1. # pacman -Syu "bind>=9.16.15-1" The problems have been fixed upstream in version 9.16.15. Workaround ========== CVE-2021-25216 is not vulnerable in the default configuration. Disabling GSS-TSIG is a viable workaround for this vulnerability. Description =========== - CVE-2021-25214 (denial of service) Incremental zone transfers (IXFR) provide a way of transferring changed portion(s) of a zone between servers. An IXFR stream containing SOA records with an owner name other than the transferred zone's apex may cause the receiving named server to inadvertently remove the SOA record for the zone in question from the zone database. This leads to an assertion failure when the next SOA refresh query for that zone is made. In BIND before version 9.16.14, when a vulnerable version of named receives a malformed IXFR triggering the flaw described above, the named process will terminate due to a failed assertion the next time the transferred secondary zone is refreshed. - CVE-2021-25215 (denial of service) DNAME records, described in RFC 6672, provide a way to redirect a subtree of the domain name tree in the DNS. A flaw in the way "named" processes these records may trigger an attempt to add the same RRset to the ANSWER section more than once. In BIND before version 9.16.14, when a vulnerable version of "named" receives a query for a record triggering the flaw described above, the "named" process will terminate due to a failed assertion check. - CVE-2021-25216 (arbitrary code execution) BIND servers before version 9.16.14 are vulnerable if they are running an affected version and are configured to use GSS-TSIG features. In a configuration which uses BIND's default settings the vulnerable code path is not exposed, but a server can be rendered vulnerable by explicitly setting values for the tkey-gssapi-keytab or tkey-gssapi- credential configuration options. Although the default configuration is not vulnerable, GSS-TSIG is frequently used in networks where BIND is integrated with Samba, as well as in mixed-server environments that combine BIND servers with Active Directory domain controllers. For servers that meet these conditions, the ISC SPNEGO implementation is vulnerable to various attacks, depending on the CPU architecture for which BIND was built: For named binaries compiled for 64-bit platforms, this flaw can be used to trigger a buffer over-read, leading to a server crash. Impact ====== Attackers are able to crash the named process during an IXFR (incremental zone transfer) session via a malformed request or query record. In addition, an attacker is able to execute arbitrary code on a bind server that is configured to use GSS-TSIG features (such as those configurations enabled for networks using Samba and Kerberos).

Arch Linux Security Advisory ASA-202104-4 ========================================= Severity: High Date : 2021-04-29 CVE-ID : CVE-2021-23961 CVE-2021-23994 CVE-2021-23995 CVE-2021-23998 CVE-2021-23999 CVE-2021-24002 CVE-2021-29946 CVE-2021-29948 Package : thunderbird Type : multiple issues Remote : Yes Link : https://security.archlinux.org/AVG-1836 Summary ======= The package thunderbird before version 78.10.0-1 is vulnerable to multiple issues including arbitrary code execution, arbitrary command execution, content spoofing, information disclosure, sandbox escape, access restriction bypass and signature forgery. Resolution ========== Upgrade to 78.10.0-1. # pacman -Syu "thunderbird>=78.10.0-1" The problems have been fixed upstream in version 78.10.0. Workaround ========== None. Description =========== - CVE-2021-23961 (information disclosure) A security issue was found in Firefox before version 85.0. Further techniques that built on the slipstream research combined with a malicious webpage could have exposed both an internal network's hosts as well as services running on the user's local machine. - CVE-2021-23994 (arbitrary code execution) A security issue has been found in Firefox before version 88 and Thunderbird before version 78.10. A WebGL framebuffer was not initialized early enough, resulting in memory corruption and an out of bounds write. - CVE-2021-23995 (arbitrary code execution) A security issue has been found in Firefox before version 88 and Thunderbird before version 78.10. When Responsive Design Mode was enabled, it used references to objects that were previously freed. Mozilla presumes that with enough effort this could have been exploited to run arbitrary code. - CVE-2021-23998 (content spoofing) A security issue has been found in Firefox before version 88 and Thunderbird before version 78.10. Through complicated navigations with new windows, an HTTP page could have inherited a secure lock icon from an HTTPS page. - CVE-2021-23999 (sandbox escape) A security issue has been found in Firefox before version 88 and Thunderbird before version 78.10. If a Blob URL was loaded through some unusual user interaction, it could have been loaded by the System Principal and granted additional privileges that should not be granted to web content. - CVE-2021-24002 (arbitrary command execution) A security issue has been found in Firefox before version 88 and Thunderbird before version 78.10. When a user clicked on an FTP URL containing encoded newline characters (%0A and %0D), the newlines would have been interpreted as such and allowed arbitrary commands to be sent to the FTP server. - CVE-2021-29946 (access restriction bypass) A security issue has been found in Firefox before version 88 and Thunderbird before version 78.10. Ports that were written as an integer overflow above the bounds of a 16-bit integer could have bypassed port blocking restrictions when used in the Alt-Svc header. - CVE-2021-29948 (signature forgery) A security issue has been found in Thunderbird before version 78.10. Signatures are written to disk before and read during verification, which might be subject to a race condition when a malicious local process or user is replacing the file. Impact ====== An attacker is able to execute arbitrary code, spoof context, escape the sandbox, and bypass port blocking restrictions through various means. In addition a local attacker might spoof the verification of emails signed using PGP by winning a race condition.

Resolution ========== Upgrade to 88.0-1. # pacman -Syu "firefox>=88.0-1" The problems have been fixed upstream in version 88.0. Workaround ========== None. Description =========== - CVE-2021-23994 (arbitrary code execution) A security issue has been found in Firefox before version 88 and Thunderbird before version 78.10. A WebGL framebuffer was not initialized early enough, resulting in memory corruption and an out of bounds write. - CVE-2021-23995 (arbitrary code execution) A security issue has been found in Firefox before version 88 and Thunderbird before version 78.10. When Responsive Design Mode was enabled, it used references to objects that were previously freed. Mozilla presumes that with enough effort this could have been exploited to run arbitrary code. - CVE-2021-23996 (content spoofing) A security issue has been found in Firefox before version 88. By utilizing 3D CSS in conjunction with Javascript, content could have been rendered outside the webpage's viewport, resulting in a spoofing attack that could have been used for phishing or other attacks on a user. - CVE-2021-23997 (arbitrary code execution) A security issue has been found in Firefox before version 88. Due to unexpected data type conversions, a use-after-free could have occurred when interacting with the font cache. Mozilla presumes that with enough effort this could have been exploited to run arbitrary code. - CVE-2021-23998 (content spoofing) A security issue has been found in Firefox before version 88 and Thunderbird before version 78.10. Through complicated navigations with new windows, an HTTP page could have inherited a secure lock icon from an HTTPS page. - CVE-2021-23999 (sandbox escape) A security issue has been found in Firefox before version 88 and Thunderbird before version 78.10. If a Blob URL was loaded through some unusual user interaction, it could have been loaded by the System Principal and granted additional privileges that should not be granted to web content. - CVE-2021-24000 (content spoofing) A security issue has been found in Firefox before version 88. A race condition with requestPointerLock() and setTimeout() could have resulted in a user interacting with one tab when they believed they were on a separate tab. In conjunction with certain elements (such as <input type="file">) this could have led to an attack where a user was confused about the origin of the webpage and potentially disclosed information they did not intend to. - CVE-2021-24001 (sandbox escape) A security issue has been found in Firefox before version 88. A compromised content process could have performed session history manipulations it should not have been able to due to testing infrastructure that was not restricted to testing-only configurations. - CVE-2021-24002 (arbitrary command execution) A security issue has been found in Firefox before version 88 and Thunderbird before version 78.10. When a user clicked on an FTP URL containing encoded newline characters (%0A and %0D), the newlines would have been interpreted as such and allowed arbitrary commands to be sent to the FTP server. - CVE-2021-29946 (access restriction bypass) A security issue has been found in Firefox before version 88 and Thunderbird before version 78.10.
