Synopsis
========
Multiple vulnerabilities in Cscope might allow for the remote execution
of arbitrary code.

Background
==========
Cscope is a developer's tool for browsing source code.

Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-util/cscope < 15.7a >= 15.7a

Description
===========
James Peach of Apple discovered a stack-based buffer overflow in
cscope's handling of long file system paths (CVE-2009-0148). Multiple
stack-based buffer overflows were reported in the putstring function
when processing an overly long function name or symbol in a source code
file (CVE-2009-1577).

Impact
======
A remote attacker could entice a user to open a specially crafted
source file, possibly resulting in the remote execution of arbitrary
code with the privileges of the user running the application.

Workaround
==========
There is no known workaround at this time.

Resolution
==========
All Cscope users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-util/cscope-15.7a"
