ID:	200705-02

Synopsis

A vulnerability has been discovered in FreeType allowing for user-assisted remote execution of arbitrary code.

Background

FreeType is a True Type Font rendering library.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
media-libs/freetype	< 2.1.10-r3	>= 2.1.10-r3	All supported architectures

Description

Greg MacManus of iDefense Labs has discovered an integer overflow in the function bdfReadCharacters() when parsing BDF fonts.

Impact

A remote attacker could entice a user to use a specially crafted BDF font, possibly resulting in a heap-based buffer overflow and the remote execution of arbitrary code.

Workaround

There is no known workaround at this time.

Resolution

All FreeType users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=media-libs/freetype-2.1.10-r3"
