Description Agostino Sarubbo gentoo-dev

2016-10-06 15:50:04 UTC

From https://bugzilla.redhat.com/show_bug.cgi?id=1382006:

It was found that in storage.c, the image size is not checked for negative values. This can lead to a null pointer dereference in 3.3.x, or a dereference 
of junk memory prior to that.

Upstream patch:

https://github.com/python-pillow/Pillow/commit/5d8a0be45aad78c5a22c8d099118ee26ef8144af


From https://bugzilla.redhat.com/show_bug.cgi?id=1382000:

Integer overflow vulnerabilities were found in PyImaging_MapBuffer function, specifically there's unchecked multiplication of xsize * ysize * 
bytes_per_pixel where the sizes are each an int as well as unchecked addition of the size calculated above with a attacker provided offset value.

Upstream patch:

https://github.com/python-pillow/Pillow/commit/c50ebe6459a131a1ea8ca531f10da616d3ceaa0f


@maintainer(s): after the bump, in case we need to stabilize the package, please let us know if it is ready for the stabilization or not.

The two vulnerabilities were already reported in bug 599608 and bug 599610 so closing as duplicate.
