Severity: normal
Exploitable: remote
Date: November 24, 2006
Bug(s): #154573
ID: 200611-20

Synopsis

GNU gv improperly handles user-supplied data possibly allowing for the execution of arbitrary code.

Background

GNU gv is a viewer for PostScript and PDF documents.

Affected Packages

Package: app-text/gv
Vulnerable: < 3.6.2-r1
Unaffected: >= 3.6.2-r1
Architectures: All supported architectures


Description

GNU gv does not properly boundary check user-supplied data before copying it into process buffers.

Impact

An attacker could entice a user to open a specially crafted document with GNU gv and execute arbitrary code with the rights of the user on the system.

Workaround

There is no known workaround at this time.

Resolution

All gv users should upgrade to the latest version:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-text/gv-3.6.2-r1"
