+
+Package: fetchmail
+Vulnerability: denial of service
+OpenPKG Specific: no
+
+Affected Releases: Affected Packages: Corrected Packages:
+OpenPKG CURRENT <= fetchmail-6.2.4-20031008 >= fetchmail-6.2.5-20031016
+OpenPKG 1.3 <= fetchmail-6.2.3-1.3.0 >= fetchmail-6.2.3-1.3.1
+
+Dependent Packages: none
+
+Description:
+ According to Mandrake security advisory MDKSA-2003:101 [0], a
+ denial of service vulnerability exists in the header rewriting
+ code of fetchmail [1]. The code's intention is to hack message
+ headers so replies work properly. However, logic in the reply_hack
+ function fails to allocate enough memory for long lines and may
+ write past a memory boundary. This could allow an attacker to
+ cause a denial of service by sending a specially crafted email
+ and crashing fetchmail.
+
+ The Common Vulnerabilities and Exposures (CVE) project assigned
+ the id CAN-2003-0792 [2] to the problem.
+
+ Please check whether you are affected by running "<prefix>/bin/rpm
+ -q fetchmail". If you have the "fetchmail" package installed and its
+ version is affected (see above), we recommend that you immediately
+ upgrade it (see Solution). [3][4]
+
+Solution:
+ 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 OpenPKG 1.3 release, perform the following operations to
+ permanently fix the security problem.
+
+ $ ftp ftp.openpkg.org
+ ftp> bin
+ ftp> cd release/1.3/UPD
+ ftp> get fetchmail-6.2.3-1.3.1.src.rpm
+ ftp> bye
+ $ <prefix>/bin/openpkg rpm -v --checksig fetchmail-6.2.3-1.3.1.src.rpm
+ $ <prefix>/bin/openpkg rpm --rebuild fetchmail-6.2.3-1.3.1.src.rpm
+ $ su -
+ # <prefix>/bin/openpkg rpm -Fvh <prefix>/RPM/PKG/fetchmail-6.2.3-1.3.1.*.rpm
