Bug 390623 – <media-libs/freetype-2.4.8 CID-keyed Font Parsing Vulnerabilities (CVE-2011-3439)

• Status: RESOLVED FIXED
• Product: Gentoo Security

[Description Agostino Sarubbo 2011-11-15 16:16:24 UTC]

From secunia security advisory at $URL:

Description:
The vulnerabilities are caused due to errors in src/cid/cidload.c when parsing CID-keyed Type 1 fonts. This can be exploited to corrupt memory via a specially crafted font file.

Successful exploitation may allow execution of arbitrary code.

The vulnerabilities are reported in versions prior to 2.4.8.

Solution:
Update to version 2.4.8

Thanks, everyone. Added to existing GLSA request.

This issue was resolved and addressed in
 GLSA 201201-09 at http://security.gentoo.org/glsa/glsa-201201-09.xml
by GLSA coordinator Sean Amoss (ackle).

@fonts, @tex.

Bug 400883 was opened because a GLSA [1] indicates that freetype 1 is affected by these vulnerabilities. If not these vulnerabilities, it is most likely affected by /some/ vulnerabilities. 

What options do we have for freetype:1 given its lack of upstream support [2] and the small number of packages that require it? I believe only games-action/heavygear2 and app-text/texlive depend on freetype:1.

Or do we do nothing, leave freetype:1 and texlive as is and reported as vulnerable by glsa-check?

Thanks much.

First determine that freetype:1 is actually vulnerable.

[Comment 16 Ryan Hill (RETIRED) 2012-02-05 19:50:07 UTC]

I don't think this version supported CID-keyed fonts.  The only mention of them I can find is in a comment.

(In reply to comment #15)
> First determine that freetype:1 is actually vulnerable.

It may or may not be vulnerable to this issue, but is likely vulnerable to at least one of the 2.x vulnerabilities that have been disclosed since support for freetype:1 stopped. 

Is moving away from freetype:1 an option, or do we need to look at all the recent freetype:2 vulnerabilities to see which apply?
