The png_check_keyword function in pngwutil.c in libpng before 1.0.42, and 1.2.x before 1.2.34, might allow context-dependent attackers to set the value of an arbitrary memory location to zero via vectors involving creation of crafted PNG files with keywords, related to an implicit cast of the '\0' character constant to a NULL pointer. NOTE: some sources incorrectly report this as a double free vulnerability.

Security readout for executives and security teams

CVE-2008-5907 is a libpng memory-corruption issue triggered when creating crafted PNG files with keywords. Affected versions are libpng before 1.0.42 and 1.2.x before 1.2.34. The source bundle does not provide CVSS scoring or confirmed active exploitation, but libpng is commonly embedded in image-handling software. Exposure is most likely where systems generate or process PNG files using vulnerable libpng versions, including software with bundled or statically linked libpng. The bundle names libpng versions, not specific downstream applications. Treat this as a routine but real dependency risk. Prioritize internet-facing or user-upload image-processing systems first, then complete normal patch hygiene for older platforms and bundled dependencies. Mitigation focus: Upgrade libpng to 1.0.42, 1.2.34, or later supported versions.; Apply relevant operating system vendor security updates where libpng is packaged.; Inventory applications that bundle or statically link libpng..
