1. Gentoo Linux Security Advisory

Package	Vulnerable versions	Unaffected versions	Architecture(s)
net-proxy/squidclamav	< 6.8	>= 6.8	All supported architectures

Related bugreports: #428778

A vulnerability in SquidClamav may result in Denial of Service.

2. Impact Information

SquidClamav is a HTTP anti-virus for Squid based on ClamAV and ICAP.

SquidClamav does not properly escape URLs before passing them to the system command call.

A remote attacker could send a specially crafted URL to SquidClamav, possibly resulting in a Denial of Service condition.

3. Resolution Information

There is no known workaround at this time.

All SquidClamav users should upgrade to the latest version:

Code Listing 3.1: Resolution

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=net-proxy/squidclamav-6.8"
