Description David Walser 2015-05-13 16:18:47 CEST

+++ This bug was initially created as a clone of Bug #15910 +++

An advisory has been issued today (May 11):
http://www.ocert.org/advisories/ocert-2015-006.html

Patched package uploaded for Mageia 4.  Updated package uploaded for Cauldron.

Advisory:
========================

Updated libraw packages fix security vulnerability:

The dcraw tool suffers from an integer overflow condition which lead to a
buffer overflow. The vulnerability concerns the 'len' variable, parsed without
validation from opened images, used in the ljpeg_start() function. A
maliciously crafted raw image file can be used to trigger the vulnerability,
causing a Denial of Service condition (CVE-2015-3885).

LibRaw contains a bundled copy of the affected code.  The libraw package has
been patched to fix this issue.

Comment 1 claire robinson 2015-05-13 16:33:00 CEST

Can be tested by opening raw type images using shotwell, which requires libraw9, and luminance-hdr, which requires libraw_r9. Also raw-identify from libraw-tools.

Whiteboard: (none) => has_procedure

Comment 2 claire robinson 2015-05-13 16:58:26 CEST

Testing complete mga4 64

Tested with nomacs rather than shotwell, others as comment 1.

Whiteboard: has_procedure => has_procedure mga4-64-ok
