Mandrakelinux Security Update Advisory

Package name: squid
Advisory ID: MDKSA-2004:112
Date: October 21st, 2004
Affected versions: 10.0, 9.2, Corporate Server 2.1,
Multi Network Firewall 8.2
______________________________________________________________________
Problem Description:
iDEFENSE discovered a Denial of Service vulnerability in squid version
2.5.STABLE6 and previous. The problem is due to an ASN1 parsing error
where certain header length combinations can slip through the
validations performed by the ASN1 parser, leading to the server
assuming there is heap corruption or some other exceptional condition,
and closing all current connections then restarting.
Squid 2.5.STABLE7 has been released to address this issue; the provided
packages are patched to fix the issue.
