CVE-2013-7424: GNU Glibc

Medium severity, CVSS 5.1. EPSS: 2.7% chance of exploitation in the next 30 days.

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.

Affected products

• GNU Glibc: up to and including 2.14.1
