Two vulnerabilities have been found in Squid which make it susceptible to Denial of Service attacks.
Package | net-proxy/squid on all architectures |
---|---|
Affected versions | < 2.6.7 |
Unaffected versions | >= 2.6.7 |
Squid is a multi-protocol proxy server.
Squid fails to correctly handle ftp:// URI's. There is also an error in the external_acl queue which can cause an infinite looping condition.
An attacker could attempt to retrieve a specially crafted URI via a Squid server causing the service to crash. If an attacker could generate a sufficiently high load on the Squid services, they could cause a Denial of Service by forcing Squid into an infinite loop.
There is no known workaround at this time.
All Squid users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-proxy/squid-2.6.7"
