Mandriva Linux Security Advisory 2015-211 – glusterfs was vulnerable to a fragment header infinite loop denial of service attack. Also, the glusterfsd SysV init script was failing to properly start the service. This was fixed by replacing it with systemd unit files for the service that work properly.

Ubuntu Security Notice 2580-1 – It was discovered that tcpdump incorrectly handled printing certain packets. A remote attacker could use this issue to cause tcpdump to crash, resulting in a denial of service, or possibly execute arbitrary code. In the default installation, attackers would be isolated by the tcpdump AppArmor profile.

UniPDF version 1.2 buffer overflow SEH overwrite denial of service proof of concept exploit.

Mandriva Linux Security Advisory 2015-210 – A denial of service flaw was found in the way QEMU handled malformed Physical Region Descriptor Table data sent to the host’s IDE and/or AHCI controller emulation. A privileged guest user could use this flaw to crash the system. It was found that the QEMU’s websocket frame decoder processed incoming frames without limiting resources used to process the header and the payload. An attacker able to access a guest’s VNC console could use this flaw to trigger a denial of service on the host by exhausting all available memory and CPU.

Mandriva Linux Security Advisory 2015-209 – Update PHP packages address buffer over-read and overflow vulnerabilities. PHP has been updated to version 5.5.24, which fixes these issues and other bugs. Additionally the timezonedb packages has been upgraded to the latest version and the PECL packages which requires so has been rebuilt for php-5.5.24.

Mandriva Linux Security Advisory 2015-208 – An issue has been identified in Mandriva Business Server 2’s setup package where the /etc/shadow and /etc/gshadow files containing password hashes were created with incorrect permissions, making them world-readable. This update fixes this issue by enforcing that those files are owned by the root user and shadow group, and are only readable by those two entities. Note that this issue only affected new Mandriva Business Server 2 installations. Systems that were updated from previous Mandriva versions were not affected. This update was already issued as MDVSA-2015:184, but the latter was withdrawn as it generated.rpmnew files for critical configuration files, and rpmdrake might propose the user to use those basically empty files, thus leading to loss of passwords or partition table. This new update ensures that such.rpmnew files are not kept after the update.

Ubuntu Security Notice 2579-1 – It was discovered that autofs incorrectly filtered environment variables when using program maps. When program maps were configured, a local user could use this issue to escalate privileges. This update changes the default behavior by adding a prefix to environment variables. Sites using program maps will need to adapt to the new variable names, or revert to the previous names by using a new configuration option called FORCE_STANDARD_PROGRAM_MAP_ENV. Various other issues were also addressed.

Mandriva Linux Security Advisory 2015-205 – disgleirio discovered that a malicious client could trigger an assertion failure in a Tor instance providing a hidden service, thus rendering the service inaccessible. DonnchaC discovered that Tor clients would crash with an assertion failure upon parsing specially crafted hidden service descriptors. Introduction points would accept multiple INTRODUCE1 cells on one circuit, making it inexpensive for an attacker to overload a hidden service with introductions. Introduction points now no longer allow multiple cells of that type on the same circuit. The tor package has been updated to version 0.2.4.27, fixing these issues.

Mandriva Linux Security Advisory 2015-206 – When Asterisk registers to a SIP TLS device and and verifies the server, Asterisk will accept signed certificates that match a common name other than the one Asterisk is expecting if the signed certificate has a common name containing a null byte after the portion of the common name that Asterisk expected.

Mandriva Linux Security Advisory 2015-207 – Updated perl-Module-Signature package fixes the following security Module::Signature could be tricked into interpreting the unsigned portion of a SIGNATURE file as the signed portion due to faulty parsing of the PGP signature boundaries. When verifying the contents of a CPAN module, Module::Signature ignored some files in the extracted tarball that were not listed in the signature file. This included some files in the t/ directory that would execute automatically during make test When generating checksums from the signed manifest, Module::Signature used two argument open() calls to read the files. This allowed embedding arbitrary shell commands into the SIGNATURE file that would execute during the signature verification process. Several modules were loaded at runtime inside the extracted module directory. Modules like Text::Diff are not guaranteed to be available on all platforms and could be added to a malicious module so that they would load from the ‘.’ path in @INC.
