Mandriva Linux Security Advisory : glibc (MDVSA-2015:218)

medium Nessus Plugin ID 83170

Language:

Synopsis

The remote Mandriva Linux host is missing one or more security updates.

Description

Multiple vulnerabilities has been found and corrected in glibc :

It was discovered that, under certain circumstances, glibc's getaddrinfo\(\) function would send DNS queries to random file descriptors. An attacker could potentially use this flaw to send DNS queries to unintended recipients, resulting in information disclosure or data loss due to the application encountering corrupted data (CVE-2013-7423).

A buffer overflow flaw was found in the way glibc's gethostbyname_r\(\) and other related functions computed the size of a buffer when passed a misaligned buffer as input. An attacker able to make an application call any of these functions with a misaligned buffer could use this flaw to crash the application or, potentially, execute arbitrary code with the permissions of the user running the application (CVE-2015-1781).

The updated packages provides a solution for these security issues.

Solution

Update the affected packages.
