"A flaw was found in the way Squid processed certain external ACL
helper HTTP header fields that contained a delimiter that was not a
comma. A remote attacker could issue a crafted request to the Squid
server, causing excessive CPU use (up to 100%). (CVE-2009-2855)

Note: The CVE-2009-2855 issue only affected non-default configurations
that use an external ACL helper script.

A flaw was found in the way Squid handled truncated DNS replies. A
remote attacker able to send specially crafted UDP packets to Squid's
DNS client port could trigger an assertion failure in Squid's child
process, causing that child process to exit. (CVE-2010-0308)

This update also fixes the following bugs :

  - Squid's init script returns a non-zero value when trying
    to stop a stopped service. This is not LSB compliant and
    can generate difficulties in cluster environments. This
    update makes stopping LSB compliant. (BZ#521926)

  - Squid is not currently built to support MAC address
    filtering in ACLs. This update includes support for MAC
    address filtering. (BZ#496170)

  - Squid is not currently built to support Kerberos
    negotiate authentication. This update enables Kerberos
    authentication. (BZ#516245)

  - Squid does not include the port number as part of URIs
    it constructs when configured as an accelerator. This
    results in a 403 error. This update corrects this
    behavior. (BZ#538738)

  - the error_map feature does not work if the same handling
    is set also on the HTTP server that operates in deflate
    mode. This update fixes this issue. (BZ#470843)

After installing this update, the squid service will be restarted
automatically."

"An updated squid package that fixes two security issues and several
bugs is now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having low
security impact. Common Vulnerability Scoring System (CVSS) base
scores, which give detailed severity ratings, are available for each
vulnerability from the CVE links in the References section.

Squid is a high-performance proxy caching server for web clients,
supporting FTP, Gopher, and HTTP data objects.

A flaw was found in the way Squid processed certain external ACL
helper HTTP header fields that contained a delimiter that was not a
comma. A remote attacker could issue a crafted request to the Squid
server, causing excessive CPU use (up to 100%). (CVE-2009-2855)

Note: The CVE-2009-2855 issue only affected non-default configurations
that use an external ACL helper script.

A flaw was found in the way Squid handled truncated DNS replies. A
remote attacker able to send specially crafted UDP packets to Squid's
DNS client port could trigger an assertion failure in Squid's child
process, causing that child process to exit. (CVE-2010-0308)

This update also fixes the following bugs :

* Squid's init script returns a non-zero value when trying to stop a
stopped service. This is not LSB compliant and can generate
difficulties in cluster environments. This update makes stopping LSB
compliant. (BZ#521926)

* Squid is not currently built to support MAC address filtering in
ACLs. This update includes support for MAC address filtering.
(BZ#496170)

* Squid is not currently built to support Kerberos negotiate
authentication. This update enables Kerberos authentication.
(BZ#516245)

* Squid does not include the port number as part of URIs it constructs
when configured as an accelerator. This results in a 403 error. This
update corrects this behavior. (BZ#538738)

* the error_map feature does not work if the same handling is set also
on the HTTP server that operates in deflate mode. This update fixes
this issue. (BZ#470843)

All users of squid should upgrade to this updated package, which
resolves these issues. After installing this update, the squid service
will be restarted automatically."
