ImageMagick before 7.0.5-2 uses uninitialized memory in the RLE decoder, allowing an attacker to leak sensitive information from process memory space, as demonstrated by remote attacks against ImageMagick code in a long-running server process that converts image data on behalf of multiple users. This is caused by a missing initialization step in the ReadRLEImage function in coders/rle.c.
This was on March 9th, so I guess this is already fixed in the versions in portage.

I pinged Gentoo maintainer to get at least 6.9.8-5 into the repository which contains an additional fix (7fdf9ea808caa3c81a0eb42656e5fafc59084198) I'd like to include.
BTW: Yahoo decided to drop entire imagemagick package due to this vulnerability from their servers.
