Title
=====

Four OpenPKG Security Advisories:

1. OpenPKG-SA-2006.028 - php

2. OpenPKG-SA-2006.029 - bind

3. OpenPKG-SA-2006.030 - ruby

4. OpenPKG-SA-2006.031 - libwmf

Detail
======

1.   According to a security advisory [0] from Stefan Esser of the
  Hardened-PHP project, buffer overflows exist in the programming
  language PHP [1], version 5.1.6 and below. The buffer overflows are
  in the functions htmlentities() and htmlspecialchars() and may result
  in arbitrary remote code execution. The Common Vulnerabilities and
  Exposures (CVE) project assigned the id CVE-2006-5465 [2] to the
  problem.

2.   According to a vendor security advisory [0], the DNS server BIND [1]
  (versions up to and including 9.3.2-P1) is vulnerable to the recently
  discovered OpenSSL RSA signature verification problem for which the
  Common Vulnerabilities and Exposures (CVE) project assigned the id
  CVE-2006-4339 [2].

3.   According to a vendor security information [0], a Denial of Service
  (DoS) vulnerability exists in the CGI library of the programming
  language Ruby [1], versions up to and including 1.8.5. The problem
  is triggered by sending the library an HTTP request that uses
  multipart MIME encoding and has an invalid boundary specifier that
  begins with "-" instead of "--". Once triggered it will exhaust all
  available memory resources effectively creating a DoS condition. The
  Common Vulnerabilities and Exposures (CVE) project assigned the id
  CVE-2006-5467 [2] to the problem.

4.   According to a BUGTRAQ posting [0], a vulnerability exists in the WMF
  format management library libwmf [1]. The vulnerability consists of an
  integer overflow which allows remote attackers to execute arbitrary
  code via the "MaxRecordSize" header field in a WMF format file. The
  Common Vulnerabilities and Exposures (CVE) project assigned the id
  CVE-2006-3376 [2] to the problem.

Description:
  According to a vendor security advisory [0], the DNS server BIND [1]
  (versions up to and including 9.3.2-P1) is vulnerable to the recently
  discovered OpenSSL RSA signature verification problem for which the
  Common Vulnerabilities and Exposures (CVE) project assigned the id
  CVE-2006-4339 [2].
  
  BIND uses RSA cryptography as part of its DNSSEC implementation. To
  resolve the security issue, upgrade to the corrected OpenPKG packages
  and for both your KEY and DNSKEY resource record types, generate new
  RSASHA1 and RSAMD5 keys using the "-e" option to dnssec-keygen(8) if
  the current keys were generated using the default exponent of 3. You
  can determine if your keys are vulnerable by looking at the algorithm
  (1 or 5) and the first three characters of the Base64 encoded RSA key.
  RSASHA1 (5) and RSAMD5 (1) keys that start with "AQM", "AQN", "AQO" or
  "AQP" are vulnerable.
