New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.
VPR Score: 5.2
SynopsisThe remote Mandriva Linux host is missing one or more security updates.
DescriptionMultiple 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.
SolutionUpdate the affected fetchmail, fetchmail-daemon and / or fetchmailconf packages.
