DSA-1390-1 t1lib -- buffer overflow

Date Reported:

18 Oct 2007

Affected Packages:

t1lib

Vulnerable:

Yes

Security database references:

In the Debian bugtracking system: Bug 439927.
In Mitre's CVE dictionary: CVE-2007-4033.

More information:

Hamid Ebadi discovered a buffer overflow in the intT1_Env_GetCompletePath routine in t1lib, a Type 1 font rasterizer library. This flaw could allow an attacker to crash an application using the t1lib shared libraries, and potentially execute arbitrary code within such an application's security context.

For the old stable distribution (sarge), this problem has been fixed in version 5.0.2-3sarge1.

For the stable distribution (etch), this problem has been fixed in version 5.1.0-2etch1.

We recommend that you upgrade your t1lib package.

Fixed in:

Debian GNU/Linux 3.1 (oldstable)
