Description:
Some security issues have been reported in the imageop module for Python, which can be exploited by malicious people to cause a DoS (Denial of Service) and potentially compromise a vulnerable system.
1) An integer overflow error within the "tovideo()" function can be exploited to cause a heap-based buffer overflow when specially crafted parameters are passed to the function.
Successful exploitation may allow execution of arbitrary code.
2) Multiple unspecified errors while validating arguments can be exploited to trigger segmentation faults.
The security issues are reported in versions prior to Python 2.6.
Solution:
Update to version 2.6.
Provided and/or discovered by:
1) Slythers Bro
2) Reported by the vendor.
