Description Agostino Sarubbo gentoo-dev 2017-07-28 15:10:17 UTC
From ${URL} :

GraphicsMagick 1.3.26 has a heap overflow in the WriteRGBImage() function in
coders/rgb.c when processing multiple frames that have non-identical widths.

Upstream patch:


@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.
Comment 1 Aaron Bauman (RETIRED) gentoo-dev 2018-03-26 00:35:09 UTC
Downgraded to B3 due to no PoC for ACE/RCE.

@maintainer(s), please clean the vulnerable version from the tree.
Comment 2 Aaron Bauman (RETIRED) gentoo-dev 2018-03-26 01:38:42 UTC
cleanup will be tracked in bug #640690
