Description Tomas Hoger 2007-09-19 08:41:17 UTC 
Common Vulnerabilities and Exposures assigned an identifier CVE-2007-4965 to the following vulnerability:

Multiple integer overflows in the imageop module in Python 2.5.1 and earlier
allow context-dependent attackers to cause a denial of service (application
crash) and possibly obtain sensitive information (memory contents) via crafted
arguments to (1) the tovideo method, and unspecified other vectors related to
(2) imageop.c, (3) rbgimgmodule.c, and other files, which trigger heap-based
buffer overflows.

Initial attempt at a fix for CVE 2007 4965

 I've uploaded this upstream too ... I'm not convinced it's everything that is
needed, so any security team review would be nice :)

James, please do an update for FC6 also, use 373281 for it. Thanks!
Comment 10 James Antill 2007-11-09 19:30:18 UTC 
 So given this applies to FC-6 and we want to fix that ... I assume we want to
fix RHEL-5 too? (very close to FC-6 python). I've put the patch in there too,
but I need a BZ with flags etc.
 RHEL-4 looks vulnerable too, as does RHEL-3.
