Updated packages for ggv fix a local buffer overflow when reading malformed PDF or PostScript files.
ggv is a user interface for the Ghostscript PostScript(R) interpreter used to display PostScript and PDF documents on an X Window System. Zen Parse found a local buffer overflow in gv version 3.5.8 and earlier. ggv versions 1.0.2 and earlier contain code derived from gv and therefore have the same vulnerability. An attacker can create a carefully crafted malformed PDF or PostScript file in such a way that when that file is viewed arbitrary commands can be executed. All users of ggv are advised to upgrade to the errata packages which contain a patch and are not vulnerable to this issue.
