Description

The png_handle_sCAL function in pngrutil.c in libpng 1.0.x before 1.0.55, 1.2.x before 1.2.45, 1.4.x before 1.4.8, and 1.5.x before 1.5.4 does not properly handle invalid sCAL chunks, which allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly have unspecified other impact via a crafted PNG image that triggers the reading of uninitialized memory.

• libpng libpng (>= 1.0.0 < 1.0.55) • libpng libpng (>= 1.2.0 < 1.2.45) • libpng libpng (>= 1.4.0 < 1.4.8) • libpng libpng (>= 1.5.0 < 1.5.4) • fedoraproject fedora 14 • debian debian linux 5.0 • debian debian linux 6.0 • canonical ubuntu linux 8.04 • canonical ubuntu linux 10.04 • canonical ubuntu linux 10.10 • canonical ubuntu linux 11.04
