FreeBSD : py-imaging, py-pillow -- Buffer overflow in PCD decoder (a8de962a-cf15-11e5-805c-5453ed2e2b49)

high Nessus Plugin ID 88673

Language:

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The Pillow maintainers report :

In all versions of Pillow, dating back at least to the last PIL 1.1.7 release, PcdDecode.c has a buffer overflow error.

The state.buffer for PcdDecode.c is allocated based on a 3 bytes per pixel sizing, where PcdDecode.c wrote into the buffer assuming 4 bytes per pixel. This writes 768 bytes beyond the end of the buffer into other Python object storage. In some cases, this causes a segfault, in others an internal Python malloc error.

Solution

Update the affected packages.
