Debian DLA-43-1 : eglibc security update

high Nessus Plugin ID 82190

Language:

Synopsis

The remote Debian host is missing a security update.

Description

CVE-2014-0475

Stephane Chazelas discovered that the GNU C library, glibc, processed '..' path segments in locale-related environment variables, possibly allowing attackers to circumvent intended restrictions, such as ForceCommand in OpenSSH, assuming that they can supply crafted locale settings.

CVE-2014-5119

Tavis Ormandy discovered a heap-based buffer overflow in the transliteration module loading code in eglibc, Debian's version of the GNU C Library. As a result, an attacker who can supply a crafted destination character set argument to iconv-related character conversation functions could achieve arbitrary code execution.

This update removes support of loadable gconv transliteration modules. Besides the security vulnerability, the module loading code had functionality defects which prevented it from working for the intended purpose.

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.
