CVE-2011-2690

29
FAUCET Score

CVE-2011-2690 describes a buffer overflow vulnerability in multiple versions of the libpng library (1.0.x, 1.2.x, 1.4.x, and 1.5.x) affecting products like Canonical, Debian, and Fedora. This flaw occurs when an application uses the png_rgb_to_gray function without png_set_expand, allowing remote attackers to overwrite memory with arbitrary data via a crafted PNG image. Rated with a CVSS score of 8.8 (HIGH), this vulnerability has a low attack complexity and could lead to high impact on confidentiality, integrity, and availability. There is no evidence of active exploitation, no public exploit code (Metasploit, Nuclei, ExploitDB), and minimal community discussion or media coverage.
