CVE-2009-5063: Libpng

Medium severity, CVSS 5.0. EPSS: 1.5% chance of exploitation in the next 30 days.

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.
