Synopsis

A vulnerability in Pngcrush might result in user-assisted execution of arbitrary code.

Background

Pngcrush is a multi platform optimizer for PNG (Portable Network Graphics) files.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
media-gfx/pngcrush	< 1.6.4-r1	>= 1.6.4-r1	All supported architectures

Description

It has been reported that Pngcrush includes a copy of libpng that is vulnerable to a memory corruption (GLSA 200804-15).

Impact

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.

Workaround

There is no known workaround at this time.

Resolution

All Pngcrush users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=media-gfx/pngcrush-1.6.4-r1"
