Overview

CVE-2013-7424 is a medium-severity vulnerability affecting gnu glibc. It was published on August 26, 2015 and has a CVSS 2.0 base score of 5.1 (MEDIUM).

This vulnerability has a CVSS 2.0 base score of 5.1, rated MEDIUM. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

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.

Remediation

Check the references section for vendor advisories and patches from gnu. Update glibc to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
