Description

This security bulletin contains information about 2 secuirty vulnerabilities.


1) Stack-based buffer overflow (CVE-ID: CVE-2013-1914)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error within the getaddrinfo function in sysdeps/posix/getaddrinfo.c when processing a (1) hostname or (2) IP address that triggers a large number of domain conversion results. A remote unauthenticated attacker can trigger stack-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


2) Stack-based buffer overflow (CVE-ID: CVE-2012-3480)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error when processing a long string, which triggers a stack-based buffer overflow. A remote unauthenticated attacker can trigger stack-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
