Vulnerability Assessment Details
JunkBuster: Multiple vulnerabilities
Detailed Explanation for this Vulnerability Assessment
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, a possible hacker can modify the referrer
setting by getting a victim to request a specially crafted URL
(CVE-2005-1108). Tavis Ormandy of the Gentoo Linux Security Audit Team
identified a heap corruption issue in the filtering of URLs
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.
There is no known workaround at this time.
All JunkBuster users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=www-proxy/junkbuster-2.0.2-r3"
Network Security Threat Level: High
