What is CVE-2013-7424?
CVE-2013-7424 is a medium-severity memory corruption vulnerability in Gnu Glibc, published on 26 Aug 2015. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official 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.
Weakness: CWE-17
