Debian DSA-2058-1 : glibc, eglibc - multiple vulnerabilities

high Nessus Plugin ID 46861

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

Several vulnerabilities have been discovered in the GNU C Library (aka glibc) and its derivatives. The Common Vulnerabilities and Exposures project identifies the following problems :

- CVE-2008-1391, CVE-2009-4880, CVE-2009-4881 Maksymilian Arciemowicz discovered that the GNU C library did not correctly handle integer overflows in the strfmon family of functions. If a user or automated system were tricked into processing a specially crafted format string, a remote attacker could crash applications, leading to a denial of service.

- CVE-2010-0296 Jeff Layton and Dan Rosenberg discovered that the GNU C library did not correctly handle newlines in the mntent family of functions. If a local attacker were able to inject newlines into a mount entry through other vulnerable mount helpers, they could disrupt the system or possibly gain root privileges.

- CVE-2010-0830 Dan Rosenberg discovered that the GNU C library did not correctly validate certain ELF program headers. If a user or automated system were tricked into verifying a specially crafted ELF program, a remote attacker could execute arbitrary code with user privileges.

Solution

Upgrade the glibc or eglibc packages.

For the stable distribution (lenny), these problems have been fixed in version 2.7-18lenny4 of the glibc package.
