CVE-2009-5063 describes a memory leak vulnerability in libpng versions prior to 1.2.39beta5, specifically within the embedded_profile_len function in pngwutil.c. This flaw allows remote attackers to trigger a denial of service (memory leak or segmentation fault) by supplying a crafted JPEG image containing an iCCP chunk with a negative embedded profile length. Rated with a CVSS score of 5.0 (AV:N/AC:L/Au:N/C:N/I:N/A:P), it indicates a network-exploitable vulnerability with low attack complexity, leading to partial availability impact. There is no evidence of active exploitation, publicly available exploit code, or significant community discussion surrounding this vulnerability.

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.
