Severity: normal
Exploitable: remote
Date: May 30, 2007
Bug(s): #179161
ID: 200705-22

Synopsis


A vulnerability has been discovered in FreeType allowing for the execution
of arbitrary code.


Background


FreeType is a True Type Font rendering library.


Affected Packages

Package: media-libs/freetype
Vulnerable: < 2.3.4-r2
Unaffected: >= 2.3.4-r2

Description


Victor Stinner discovered a heap-based buffer overflow in the function
Get_VMetrics() in src/truetype/ttgload.c when processing TTF files with
a negative n_points attribute.


Impact


A remote attacker could entice a user to open a specially crafted TTF
file, possibly resulting in the execution of arbitrary code with the
privileges of the user running FreeType.


Workaround


There is no known workaround at this time.


Resolution


All FreeType users should upgrade to the latest version:
Code:
# emerge --sync
