Severity:	normal
Title:	CVS: Heap-based overflow
Date:	01/19/2017
Bugs:	#402593
ID:	201701-44

Synopsis

A heap-based buffer overflow in CVS might allow remote attackers to execute arbitrary code.

Background

CVS (Concurrent Versions System) is an open-source network-transparent version control system. It contains both a client utility and a server.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
dev-vcs/cvs	< 1.12.12-r11	>= 1.12.12-r11	All supported architectures

Description

A heap-based buffer overflow was discovered in the proxy_connect function in src/client.c in CVS.

Impact

An attacker, utilizing a remote HTTP proxy server, could cause a Denial of Service condition or possibly execute arbitrary code via a crafted HTTP response.

Workaround

There is no known workaround at this time.

Resolution

All CVS users should upgrade to the latest version:

      # emerge --sync
      # emerge --ask --oneshot --verbose ">=dev-vcs/cvs-1.12.12-r11"
