New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

Synopsis

The remote Debian host is missing a security update.

Description

This update fixes several issues as described below.

PR ld/12613 (no CVE assigned)

Niranjan Hasabnis discovered that passing an malformed linker script to GNU ld, part of binutils, may result in a stack-based buffer overflow. If the linker is used with untrusted object files, this would allow remote attackers to cause a denial of service (crash) or possibly privilege escalation.

CVE-2012-3509 #688951

Sang Kil Cha discovered that a buffer size calculation in libiberty, part of binutils, may result in integer overflow and then a heap buffer overflow. If libiberty or the commands in binutils are used to read untrusted binaries, this would allow remote attackers to cause a denial of service (crash) or possibly privilege escalation.

PR binutils/18750 (no CVE assigned)

Joshua Rogers reported that passing a malformed ihex (Intel hexadecimal) file to to various commands in binutils may result in a stack-based buffer overflow. A similar issue was found in readelf. If these commands are used to read untrusted binaries, this would allow remote attackers to cause a denial of service (crash) or possibly privilege escalation.

For the oldoldstable distribution (squeeze), these problems have been fixed in version 2.20.1-16+deb6u2.

For the oldstable distribution (wheezy) and the stable distribution (jessie), PR ld/12613 and CVE-2012-3509 were fixed before release, and PR binutils/18750 will be fixed in a later update.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
