GLSA-200504-11 : JunkBuster: Multiple vulnerabilities

high Nessus Plugin ID 18044

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200504-11 (JunkBuster: Multiple vulnerabilities)

 James Ranson reported a vulnerability when JunkBuster is configured to run in single-threaded mode, an attacker can modify the referrer setting by getting a victim to request a specially crafted URL (CAN-2005-1108). Tavis Ormandy of the Gentoo Linux Security Audit Team identified a heap corruption issue in the filtering of URLs (CAN-2005-1109).
 Impact :

 If JunkBuster has been configured to run in single-threaded mode, an attacker can disable or modify the filtering of Referrer: HTTP headers, potentially compromising the privacy of users. The heap corruption vulnerability could crash or disrupt the operation of the proxy, potentially executing arbitrary code.
 Workaround :

 There is no known workaround at this time.

Solution

All JunkBuster users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=net-proxy/junkbuster-2.0.2-r3'
