CVE-2013-7424

Status: ModifiedMedium (5.1)—

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.

CVSS

Version: 2.0
Vector: AV:N/AC:H/Au:N/C:P/I:P/A:P
Base score: 5.1

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 2.68%
Percentile among all scored CVEs: 85
Score date: 10/7/2026

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
