libpng PNG file denial of service
|libpng-png-file-dos (68536)||Medium Risk|
libpng is vulnerable to a denial of service, caused by an error when processing invalid sCAL chunks. By persuading a victim to view a specially-crafted PNG image file, a remote attacker could exploit this vulnerability to cause the application to crash.
Denial of Service
Upgrade to the latest version of libpng (1.5.4, 1.4.8, 1.2.45 or 1.0.55 or later), available from the libpng Web site. See References.
