Arch Linux Security Advisory ASA-201412-17 ========================================== Severity: Medium Date : 2014-12-16 CVE-ID : CVE-2014-3580 CVE-2014-8108 Package : subversion Type : denial of service Remote : Yes Link : https://wiki.archlinux.org/index.php/CVE-2014 Summary ======= The package subversion before version 1.8.11-1 is vulnerable to denial of service in mod_dav_svn through multiple remotely triggerable crashes. Resolution ========== Upgrade to 1.8.11-1. # pacman -Syu "subversion>=1.8.11-1" The problems have been fixed upstream in version 1.8.11. Workaround ========== None. Description =========== - CVE-2014-3580 (denial of service) A NULL pointer dereference flaw was found in the way mod_dav_svn handled REPORT requests. A remote, unauthenticated attacker could use a crafted REPORT request to crash mod_dav_svn. - CVE-2014-8108 (denial of service) A NULL pointer dereference flaw was found in the way mod_dav_svn handled URIs for virtual transaction names. A remote, unauthenticated attacker could send a request for a virtual transaction name that does not exist, causing mod_dav_svn to crash. Impact ====== A remote attacker is able to send specially crafted requests causing mod_dav_svn to crash leading to denial of service.

Arch Linux Security Advisory ASA-201412-16 ========================================== Severity: Medium Date : 2014-12-15 CVE-ID : CVE-2014-9356 CVE-2014-9357 CVE-2014-9358 Package : docker Type : multiple issues Remote : No Link : https://wiki.archlinux.org/index.php/CVE-2014 Summary ======= The package docker before version 1:1.4.0-1 is vulnerable to multiple issues including but not limited to privilege escalation and path traversal. Resolution ========== Upgrade to 1:1.4.0-1. # pacman -Syu "docker>=1:1.4.0-1" The problems have been fixed upstream in version 1.4.0. Workaround ========== None. Description =========== - CVE-2014-9356 (path traversal) Path traversal attacks are possible in the processing of absolute symlinks. In checking symlinks for traversals, only relative links were considered. This allowed path traversals to exist where they should have otherwise been prevented. This was exploitable via both archive extraction and through volume mounts. This vulnerability allowed malicious images or builds from malicious Dockerfiles to write files to the host system and escape containerization, leading to privilege escalation. - CVE-2014-9357 (privilege escalation) It has been discovered that the introduction of chroot for archive extraction in Docker 1.3.2 had introduced a privilege escalation vulnerability. Malicious images or builds from malicious Dockerfiles could escalate privileges and execute arbitrary code as a privileged root user on the Docker host by providing a malicious ‘xz’ binary. - CVE-2014-9358 (path traversal) It has been discovered that Docker does not sufficiently validate Image IDs as provided either via 'docker load' or through registry communications. This allows for path traversal attacks, causing graph corruption and manipulation by malicious images, as well as repository spoofing attacks. Impact ====== A local attacker is able to create malicious Dockerfiles or image IDs in order to perform privilege escalation or path traversal.

Arch Linux Security Advisory ASA-201412-15 ========================================== Severity: Medium Date : 2014-12-15 CVE-ID : CVE-2013-1752 CVE-2013-1753 CVE-2014-9365 Package : python2 Type : multiple issues Remote : Yes Link : https://wiki.archlinux.org/index.php/CVE-2014 Summary ======= The package python2 before version 2.7.9-1 is vulnerable to denial of service and man-in-the-middle attacks. Resolution ========== Upgrade to 2.7.9-1. # pacman -Syu "python2>=2.7.9-1" The problems have been fixed upstream in version 2.7.9. Workaround ========== None. Description =========== - CVE-2013-1752 (denial of service) Multiple unbound readline() flaws in python stdlib were found, which can lead to excessive memory usage if a malicious or broken server sends excessively long lines without any line breaks. - CVE-2013-1753 (denial of service) The XMLRPC library is vulnerable to unrestricted decompression of HTTP responses using gzip enconding. A malicious server can send a specially prepared HTTP request that can result in memory exhaustion. - CVE-2014-9365 (man-in-the-middle) When Python's standard library HTTP clients (httplib, urllib, urllib2, xmlrpclib) are used to access resources with HTTPS, by default the certificate is not checked against any trust store, nor is the hostname in the certificate checked against the requested host. It was possible to configure a trust root to be checked against, however there were no faculties for hostname checking. This made MITM attacks against the HTTP clients trivial, and violated RFC 2818. Impact ====== An remote attacker is able to perform a man-in-the-middle attack or cause a denial of service.

[arch-security] [Arch Linux Security Advisory ASA-201412-9] powerdns-recursor: denial of service

Arch Linux Security Advisory ASA-201412-9 ========================================= Severity: High Date : 2014-12-09 CVE-ID : CVE-2014-8601 Package : powerdns-recursor Type : denial of service Remote : Yes Link : https://wiki.archlinux.org/index.php/CVE-2014 Summary ======= The package powerdns-recursor before version 3.6.2-1 is vulnerable to remote denial of service. Resolution ========== Upgrade to 3.6.2-1. # pacman -Syu "powerdns-recursor>=3.6.2-1" The problem has been fixed upstream in version 3.6.2. Workaround ========== Only clients in allow-from are able to trigger the degraded service, so this should be limited to your user base. Description =========== PowerDNS, while acting as a caching nameserver, can be negatively impacted by sending queries for specially configured, hard to resolve domain names. This is the same issue as the ones found in bind (ASA-201412-7) and unbound (ASA-201412-8). Impact ====== A remote attacker can trick unbound into consuming a lot of resources by sending a specially crafted query.

[arch-security] [Arch Linux Security Advisory ASA-201412-8] unbound: denial of service

09 Dec '14

Arch Linux Security Advisory ASA-201412-8 ========================================= Severity: High Date : 2014-12-09 CVE-ID : CVE-2014-8602 Package : unbound Type : denial of service Remote : Yes Link : https://wiki.archlinux.org/index.php/CVE-2014 Summary ======= The package unbound before version 1.5.1-1 is vulnerable to denial of service. Resolution ========== Upgrade to 1.5.1-1. # pacman -Syu "unbound>=1.5.1-1" The problem has been fixed upstream in version 1.5.1. Workaround ========== A very simple workaround is to ignore the problem and let existing anti-DoS systems in unbound deal with the issue. It will consume a lot of resources, but other customers will (most likely) continue to get service. If affected, unbound-control flush_requestlist provides temporary relief, but the issue could resume (immediately). Putting the maliciously sent query in local-data, or using access-control to block the malicious query sending IP would workaround that exploit set-up. The config statement do-not-query-address: IPorNetblock can be used to block a specific authority server. Description =========== The resolver can be tricked into following an endless series of delegations, this consumes a lot of resources. Resolvers fetch the content for domain names by sending queries to authority servers on the internet. One of the responses that authority servers can return is a referral response, which points to further servers to continue the lookup. To continue the lookup, resolvers may have to perform recursion, where new names, called glue, from the referral response have to be looked up to continue the query resolution. The issue here is a lack of limiting on the recursion fetches performed to figure out a particular query. The authority server is a special set-up that responds with an infinite amount of glue. This then causes the resolver to spend a lot of resources diving into the infinite glue looking up names, only find out it needs to look up even more names. Impact ====== A remote attacker can trick unbound into consuming a lot of resources by sending a specially crafted query.
