CWE-401Published: August 31, 2011· Updated: Jun 16, 2026
5.0
CVSS v3.1
Official Description
Memory leak in the embedded_profile_len function in pngwutil.c in libpng before 1.2.39beta5 allows context-dependent attackers to cause a denial of service (memory leak or segmentation fault) via a JPEG image containing an iCCP chunk with a negative embedded profile length. NOTE: this is due to an incomplete fix for CVE-2006-7244.
Technical Analysis
CVE-2009-5063 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
