Pardus: cups Buffer Overflow Print E-mail
User Rating:      How can I rate this item?
Posted by Bill Keys   
There is a potential integer overflow in the validation code that could render the whole validation useless. IInteger overflow in the _cupsImageReadPNG function in CUPS 1.1.17 through 1.3.9 allows remote attackers to execute arbitrary code via a PNG image with a large height value, which bypasses a validation check and triggers a buffer overflow.
