-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ Mandriva Linux Security Advisory MDVSA-2013:037 http://www.mandriva.com/en/support/security/ _______________________________________________________________________ Package : fetchmail Date : April 5, 2013 Affected: Business Server 1.0 _______________________________________________________________________ Problem Description: Multiple vulnerabilities has been found and corrected in fetchmail: Fetchmail version 6.3.9 enabled all SSL workarounds (SSL_OP_ALL) which contains a switch to disable a countermeasure against certain attacks against block ciphers that permit guessing the initialization vectors, providing that an attacker can make the application (fetchmail) encrypt some data for him -- which is not easily the case (aka a BEAST attack) (CVE-2011-3389). A denial of service flaw was found in the way Fetchmail, a remote mail retrieval and forwarding utility, performed base64 decoding of certain NTLM server responses. Upon sending the NTLM authentication request, Fetchmail did not check if the received response was actually part of NTLM protocol exchange, or server-side error message and session abort. A rogue NTML server could use this flaw to cause fetchmail executable crash (CVE-2012-3482). This advisory provides the latest version of fetchmail (6.3.22) which is not vulnerable to these issues. _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2011-3389 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-3482 http://www.fetchmail.info/fetchmail-SA-2012-01.txt http://www.fetchmail.info/fetchmail-SA-2012-02.txt _______________________________________________________________________ Updated Packages: Mandriva Business Server 1/X86_64: c30dacec397667ad6058f3800f3aca2c mbs1/x86_64/fetchmail-6.3.22-1.mbs1.x86_64.rpm bed6bf2974ebcb9ac9c8f5e2c2ee310b mbs1/x86_64/fetchmailconf-6.3.22-1.mbs1.x86_64.rpm 1750ed3c0d237c7ac4fcf6b98a7b1b21 mbs1/x86_64/fetchmail-daemon-6.3.22-1.mbs1.x86_64.rpm dbd678a792ee058801ec35c7f99096a4 mbs1/SRPMS/fetchmail-6.3.22-1.mbs1.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
