Gentoo Linux Security Advisory

Title: Squid: Multiple Denial of Service vulnerabilities (GLSA 200701-22)
Severity: normal
Exploitable: remote
Date: January 25, 2007
Bug(s): #162364
ID: 200701-22

Synopsis


Two vulnerabilities have been found in Squid which make it susceptible to
Denial of Service attacks.


Background


Squid is a multi-protocol proxy server.


Affected Packages

Package: net-proxy/squid
Vulnerable: < 2.6.7
Unaffected: >= 2.6.7
Architectures: All supported architectures


Description


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.


Impact


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.


Workaround


There is no known workaround at this time.


Resolution


All Squid users should upgrade to the latest version:
Code:
# emerge --sync
    # emerge --ask --oneshot --verbose ">=net-proxy/squid-2.6.7"


References

CVE-2007-0247
CVE-2007-0248
