ID:	200607-08

Synopsis

GIMP is prone to a buffer overflow which may lead to the execution of arbitrary code when loading specially crafted XCF files.

Background

GIMP is the GNU Image Manipulation Program. XCF is the native image file format used by GIMP.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
media-gfx/gimp	< 2.2.12	>= 2.2.12	All supported architectures

Description

Henning Makholm discovered that the "xcf_load_vector()" function is vulnerable to a buffer overflow when loading a XCF file with a large "num_axes" value.

Impact

An attacker could exploit this issue to execute arbitrary code by enticing a user to open a specially crafted XCF file.

Workaround

There is no known workaround at this time.

Resolution

All GIMP users should update to the latest stable version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=media-gfx/gimp-2.2.12"
