Updated packages for gv and ggv fix a local buffer overflow when reading malformed PDF or PostScript(R) files. [Updated 16 April 2003] Added packages for Red Hat Linux on IBM iSeries and pSeries systems.
Both gv and ggv are applications which use the Ghostscript PostScript interpreter to display PostScript and PDF documents under the X Window System. Zen Parse found a local buffer overflow in gv version 3.5.8 and earlier. Under this vulnerability, an attacker can create a carefully crafted, malformed PDF or PostScript file that, when viewed using gv, executes arbitrary commands on the system. Because ggv contains code derived from gv, it has the same vulnerability. All users of gv and ggv are advised to upgrade to these errata packages to correct this vulnerability.
