OpenPKG Security Advisory                            The OpenPKG Project                    
OpenPKG-SA-2004.048                                          29-Oct-2004

Package:             squid (option "with_snmp yes" only)
Vulnerability:       denial of service
OpenPKG Specific:    no

Affected Releases:   Affected Packages:      Corrected Packages:
OpenPKG CURRENT      <= squid-2.5.6-20040913 >= squid-2.5.7-20041012
OpenPKG 2.2          none                    N.A.
OpenPKG 2.1          <= squid-2.5.6-2.1.0    >= squid-2.5.6-2.1.1

Dependent Packages:  none

  According to an iDEFENSE security advisory [0], a denial of service
  (DoS) vulnerability exists in the Squid [1] web caching proxy [1].
  The "asn_parse_header" function in the SNMP module of Squid before
  version 2.4.STABLE7 allows remote attackers to cause a denial of
  service (server restart) via certain SNMP packets with negative
  length fields that causes a memory allocation error. The Common
  Vulnerabilities and Exposures (CVE) project assigned the id
  CAN-2004-0918 [2] to the problem.

  Please check whether you are affected by running "/bin/rpm -q
  squid" and "/bin/rpm -qi squid | grep with_snmp". If you have
  the "squid" package with option "with_snmp" installed and its version
  is affected (see above), we recommend that you immediately upgrade
  (see Solution) [3][4].

  Select the updated source RPM appropriate for your OpenPKG release
  [5], fetch it from the OpenPKG FTP service [6] or a mirror location,
  verify its integrity [7], build a corresponding binary RPM from it [3]
  and update your OpenPKG installation by applying the binary RPM [4].
  For the previous release OpenPKG 2.1, perform the following operations
  to permanently fix the security problem (for other releases adjust

  $ ftp
  ftp> bin
  ftp> cd release/2.1/UPD
  ftp> get squid-2.5.6-2.1.1.src.rpm
  ftp> bye
  $ /bin/openpkg rpm -v --checksig squid-2.5.6-2.1.1.src.rpm
  $ /bin/openpkg rpm --rebuild squid-2.5.6-2.1.1.src.rpm
  $ su -
  # /bin/openpkg rpm -Fvh /RPM/PKG/squid-2.5.6-2.1.1.*.rpm
