Description Tomas Hoger 2007-10-09 12:10:33 UTC 
Common Vulnerabilities and Exposures assigned an identifier CVE-2007-5269 to the following vulnerability:

Certain chunk handlers in libpng before 1.0.29 and 1.2.x before 1.2.21
allow remote attackers to cause a denial of service (crash) via
crafted (1) pCAL (png_handle_pCAL), (2) sCAL (png_handle_sCAL), (3)
tEXt (png_push_read_tEXt), (4) iTXt (png_handle_iTXt), and (5) ztXT
(png_handle_ztXt) chunking in PNG images, which trigger out-of-bounds
read operations.
