ImageMagick: buffer overflow flaw when handling PSD images that use RLE encoding

Buffer overflow in the DecodePSDPixels function in coders/psd.c in ImageMagick before 6.8.8-5 might allow remote attackers to execute arbitrary code via a crafted PSD image, involving the L%06ld string, a different vulnerability than CVE-2014-2030.

Insecure temp file usage in Ubuntu UI toolkit

On desktop, Ubuntu UI Toolkit's StateSaver would serialise data on tmp/ files which an attacker could use to expose potentially sensitive data. StateSaver would also open files without the O_EXCL flag. An attacker could exploit this to launch a symlink attack, though this is partially mitigated by symlink and hardlink restrictions in Ubuntu. Fixed in 1.1.1188+14.10.20140813.4-0ubuntu1.

zsh: buffer overflow for very long fds in >& fd syntax

In exec.c in zsh before 5.0.7, there is a buffer overflow for very long fds in the ">& fd" syntax.

perl-dbi: Risk of memory corruption with many arguments in DBI method dispatch

An issue was discovered in the DBI module before 1.632 for Perl. Using many arguments to methods for Callbacks may lead to memory corruption.

qemu: stellaris_enet: buffer overrun on incoming migration

Qemu 1.1.2+dfsg to 2.1+dfsg suffers from a buffer overrun which could potentially result in arbitrary code execution on the host with the privileges of the QEMU process.

glibc: stack overflow in getaddrinfo()'s use of alloca()

The eglibc package before 2.14 incorrectly handled the getaddrinfo() function. An attacker could use this issue to cause a denial of service.

Lintian before 2.5.12 allows remote attackers to gather information about the "host" system using crafted symlinks.

Potential DoS through abuse of rate limit in libunity-webapps for Firefox

The unity-firefox-extension package could be tricked into dropping a C callback which was still in use, which Firefox would then free, causing Firefox to crash. This could be achieved by adding an action to the launcher and updating it with new callbacks until the libunity-webapps rate limit was hit. Fixed in 3.0.0+14.04.20140416-0ubuntu1.14.04.1 of unity-firefox-extension and in all versions of libunity-webapps by shipping an empty unity-firefox-extension package, thus disabling the extension entirely and invalidating the attack against the libunity-webapps package.

Possible remote DOS in WebApps

The unity-firefox-extension package could be tricked into destroying the Unity webapps context, causing Firefox to crash. This could be achieved by spinning the event loop inside the webapps initialization callback. Fixed in 3.0.0+14.04.20140416-0ubuntu1.14.04.1 by shipping an empty package, thus disabling the extension entirely.

NetworkManager: creating new WPA-secured wireless network results in insecure network being created instead

In NetworkManager 0.9.2.0, when a new wireless network was created with WPA/WPA2 security in AdHoc mode, it created an open/insecure network.

A Security Bypass vulnerability exists in Ubuntu Cobbler before 2,2,2 in the cobbler-ubuntu-import script due to an error when verifying the GPG signature.

OverlayFS in the Linux kernel before 3.0.0-16.28, as used in Ubuntu 10.0.4 LTS and 11.10, is missing inode security checks which could allow attackers to bypass security restrictions and perform unauthorized actions.

fs/proc/base.c in the Linux kernel through 3.1 allows local users to obtain sensitive keystroke information via access to /proc/interrupts.

mod_perl: arbitrary Perl code execution in the context of the user account via a user-owned .htaccess

mod_perl 2.0 through 2.0.10 allows attackers to execute arbitrary Perl code by placing it in a user-owned .htaccess file, because (contrary to the documentation) there is no configuration option that permits Perl code for the administrator's control of HTTP request processing without also permitting unprivileged users to run Perl code in the context of the user account that runs Apache HTTP Server processes.

The Linux kernel from v2.3.36 before v2.6.39 allows local unprivileged users to cause a denial of service (memory consumption) by triggering creation of PTE pages.

wpa_supplicant: wpa_supplicant loading arbitrary shared objects allowing privilege escalation

An issue was discovered in Ubuntu wpa_supplicant that resulted in loading of arbitrary shared objects, which allows a local unprivileged attacker to escalate privileges to the user that wpa_supplicant runs as (usually root). Membership in the netdev group or access to the dbus interface of wpa_supplicant allow an unprivileged user to specify an arbitrary path to a module to be loaded by the wpa_supplicant process; other escalation paths might exist.
