Gentoo Linux Security Advisory GLSA 200805-08 - The namesx and uhnames modules do not properly validate network input, leading to a buffer overflow. Versions less than 1.1.19 are affected.

Gentoo Linux Security Advisory GLSA 200805-07 - LTSP version 4.2, ships prebuilt copies of programs such as the Linux Kernel, the X.org X11 server (GLSA 200705-06, GLSA 200710-16, GLSA 200801-09), libpng (GLSA 200705-24, GLSA 200711-08), Freetype (GLSA 200705-02, GLSA 200705-22) and OpenSSL (GLSA 200710-06, GLSA 200710-30) which were subject to multiple security vulnerabilities since 2006. Please note that the given list of vulnerabilities might not be exhaustive. Versions less than 5.0 are affected.

Gentoo Linux Security Advisory GLSA 200805-06 - Viesturs reported that the default configuration for Gentoo's init script (/etc/conf.d/firebird) sets the ISC_PASSWORD environment variable when starting Firebird. It will be used when no password is supplied by a client connecting as the SYSDBA user. Versions less than 2.0.3.12981.0-r6 are affected.

Mandriva Linux Security Advisory - A heap-based buffer overflow vulnerability was found in how ImageMagick parsed XCF files. If ImageMagick opened a specially-crafted XCF file, it could be made to overwrite heap memory beyond the bounds of its allocated memory, potentially allowing an attacker to execute arbitrary code on the system running ImageMagick. Another heap-based buffer overflow vulnerability was found in how ImageMagick processed certain malformed PCX images. If ImageMagick opened a specially-crafted PCX image file, an attacker could possibly execute arbitrary code on the system running ImageMagick.

Ubuntu Security Notice 611-3 - USN-611-1 fixed a vulnerability in Speex. This update provides the corresponding update for GStreamer Good Plugins. It was discovered that Speex did not properly validate its input when processing Speex file headers. If a user or automated system were tricked into opening a specially crafted Speex file, an attacker could create a denial of service in applications linked against Speex or possibly execute arbitrary code as the user invoking the program.

Ubuntu Security Notice 611-2 - USN-611-1 fixed a vulnerability in Speex. This update provides the corresponding update for ogg123, part of vorbis-tools. It was discovered that Speex did not properly validate its input when processing Speex file headers. If a user or automated system were tricked into opening a specially crafted Speex file, an attacker could create a denial of service in applications linked against Speex or possibly execute arbitrary code as the user invoking the program.

Novell Client versions 4.91 SP4 and below suffer from a local stack overflow vulnerability.

iDefense Security Advisory 05.07.08 - Remote exploitation of an integer signedness vulnerability in rdesktop, as included in various vendors' operating system distributions, allows attackers to execute arbitrary code with the privileges of the logged-in user. The vulnerability exists within the code responsible for reallocating dynamic buffers. The rdesktop xrealloc() function uses a signed comparison to determine if the requested allocation size is less than 1. When this occurs, the function will incorrectly set the allocation size to be 1. This results in an improperly sized heap buffer being allocated, which can later be overflowed. iDefense confirmed the existence of this vulnerability in rdesktop version 1.5.0. Previous versions may also be affected.

iDefense Security Advisory 05.07.08 - Remote exploitation of a BSS overflow vulnerability in rdesktop, as included in various vendors' operating system distributions, allows attackers to execute arbitrary code with the privileges of the logged-in user. The vulnerability exists within the code responsible for reading in an RDP redirect request. This request is used to redirect an RDP connection from one server to another. When parsing the redirect request, the rdesktop client reads several 32-bit integers from the request packet. These integers are then used to control the number of bytes read into statically allocated buffers. This results in several buffers located in the BSS section being overflowed, which can lead to the execution of arbitrary code. iDefense confirmed the existence of this vulnerability in rdesktop version 1.5.0. Previous versions may also be affected.
