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. Tavis
Ormandy of the Gentoo Linux Security Audit Team identified a heap
corruption issue in the filtering of URLs.
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.
Resolution
All JunkBuster users should upgrade to the latest version:
Security is a primary focus of Gentoo Linux and ensuring the
confidentiality and security of our users machines is of utmost
importance to us. Any security concerns should be addressed to
security@gentoo.org or alternatively, you may file a bug at
