Title: OptiPNG: User-assisted execution of arbitrary code (GLSA 200812-01)
Date: December 02, 2008
A vulnerability in OptiPNG might result in user-assisted execution of arbitrary code.
OptiPNG is a PNG optimizer that recompresses image files to a smaller size, without losing any information.
Vulnerable: < 0.6.2
Unaffected: >= 0.6.2
Architectures: All supported architectures
A buffer overflow in the BMP reader in OptiPNG has been reported.
A remote attacker could entice a user to process a specially crafted BMP image, possibly resulting in the execution of arbitrary code with the privileges of the user running the application, or a Denial of Service.
There is no known workaround at this time.
All OptiPNG users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=media-gfx/optipng-0.6.2"
