Vulnerability	Summary	Fixed by
VCID-kf5b-ush9-mkd1 Aliases: CVE-2011-2501	Out-of-bounds Read The png_format_buffer function in pngerror.c in libpng allows remote attackers to cause a denial of service (application crash) via a crafted PNG image that triggers an out-of-bounds read during the copying of error-message data. NOTE: this vulnerability exists because of a CVE-2004-0421 regression. NOTE: this is called an off-by-one error by some sources.	There are no reported fixed by versions.
VCID-qpn2-bwsx-1kcg Aliases: CVE-2011-2690	Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') Buffer overflow in libpng , when used by an application that calls the png_rgb_to_gray function but not the png_set_expand function, allows remote attackers to overwrite memory with an arbitrary amount of data, and possibly have unspecified other impact, via a crafted PNG image.	There are no reported fixed by versions.
VCID-uddn-ka9m-wycz Aliases: CVE-2011-2692	Improper Restriction of Operations within the Bounds of a Memory Buffer The png_handle_sCAL function in pngrutil.c in libpng 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.	There are no reported fixed by versions.
