All supported architectures
A use-after-free error in OptiPNG could result in execution of
arbitrary code or Denial of Service.
OptiPNG is a PNG optimizer that recompresses image files to a smaller
size, without losing any information.
A use-after-free vulnerability exists in the palette reduction
functionality of OptiPNG.
A remote attacker could entice a user to open a specially crafted image
file, possibly resulting in execution of arbitrary code with the
privileges of the process or a Denial of Service condition.
There is no known workaround at this time.
All OptiPNG users should upgrade to the latest version:
Code Listing 3.1: Resolution
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-gfx/optipng-0.7.3"
