Description

This security bulletin contains information about 2 secuirty vulnerabilities.


1) Input validation error (CVE-ID: CVE-2013-7424)

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

The getaddrinfo function in glibc before 2.15, when compiled with libidn and the AI_IDN flag is used, allows context-dependent attackers to cause a denial of service (invalid free) and possibly execute arbitrary code via unspecified vectors, as demonstrated by an internationalized domain name to ping6.


2) Buffer overflow (CVE-ID: CVE-2011-5320)

The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

scanf and related functions in glibc before 2.15 allow local users to cause a denial of service (segmentation fault) via a large string of 0s.
