|Gentoo Linux Security Advisory
Title: Pngcrush: User-assisted execution of arbitrary code (GLSA 200805-10)
Date: May 11, 2008
A vulnerability in Pngcrush might result in user-assisted execution of arbitrary code.
Pngcrush is a multi platform optimizer for PNG (Portable Network Graphics) files.
Vulnerable: < 1.6.4-r1
Unaffected: >= 1.6.4-r1
Architectures: All supported architectures
It has been reported that Pngcrush includes a copy of libpng that is vulnerable to a memory corruption (GLSA 200804-15).
A remote attacker could entice a user to process a specially crafted PNG 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 Pngcrush users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=media-gfx/pngcrush-1.6.4-r1"
