Gentoo: GLSA-201006-03: ImageMagick: User-assisted execution of arbitrary code
Summary
Tielei Wang has discovered that the XMakeImage() function in magick/xwindow.c is prone to an integer overflow, possibly leading to a buffer overflow.
Resolution
All ImageMagick users should upgrade to an unaffected version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-gfx/imagemagick-6.5.2.9"
NOTE: This is a legacy GLSA. Updates for all affected architectures are
available since June 4, 2009. It is likely that your system is already
no longer affected by this issue.
