Subject Name:            CVS
Subject Summary:         Concurrent Versions Systems (CVS)
Subject Home:            http://www.cvshome.org/
Subject Versions:        * <= 1.12.7

Vulnerability Id:        CVE-2004-0396
Vulnerability Scope:     global (not OpenPKG specific)

Attack Feasibility:      run-time
Attack Vector:           remote network
Attack Impact:           arbitrary code execution

Description:
    Stefan Esser discovered [1] a remote vulnerability in Concurrent
    Versions System (CVS) [0] servers. CVS up to version 1.12.7 contains
    a flaw when deciding if a CVS entry line should get a modified or
    unchanged flag attached. This results in a heap overflow which can
    be exploited to execute arbitrary code on the CVS server. This
    could allow a repository compromise.
