Description Ville Skyttä 2006-11-11 10:46:46 UTC

http://nvd.nist.gov/nvd.cfm?cvename=CVE-2006-5864

"Stack-based buffer overflow in the ps_gettext function in ps.c for GNU gv
3.6.2, and possibly earlier versions, allows user-assisted attackers to execute
arbitrary code via a PostScript (PS) file with certain headers that contain long
comments, as demonstrated using the DocumentMedia header."

Mandriva Linux Security Advisory, MDKSA-2006:214-1, says the following:

"The patch used in the previous update still left the possibility of
 causing X to consume unusual amounts of memory if gv is used to view a
 carefully crafted image designed to exploit CVE-2006-5864. This update
 uses an improved patch to address this issue."

For patches see, for example, gv-3.6.1-4.3.20060mdk.src.rpm

Thanks for the references.  Fixed in 3.6.2-2.

Comment 4 Ville Skyttä 2006-12-06 17:39:42 UTC

For info for people interested in older distros: the patch has been applied in
Extras for FC5+ only, not FC4 at the moment.
