Published: 2012-07-30 11:52:54
CVE Author: NIST National Vulnerability Database
CVSS Base Vector:
AV:N/AC:H/Au:N/C:P/I:P/A:P
Summary:
The remote host is missing an update for the 'cyrus-imapd'
Linux Distribution Package(s) announced via the referenced advisory.
Affected Versions:
cyrus-imapd on CentOS 4
Recommendations:
Please install the updated Linux Distribution Packages.
Technical Details:
The cyrus-imapd Linux Distribution Packages contain a high-performance mail server with IMAP,
POP3, NNTP, and Sieve support.
It was discovered that cyrus-imapd did not flush the received commands
buffer after switching to TLS encryption for IMAP, LMTP, NNTP, and POP3
sessions. A man-in-the-middle attacker could use this flaw to inject
protocol commands into a victim's TLS session initialization messages. This
could lead to those commands being processed by cyrus-imapd, potentially
allowing the attacker to steal the victim's mail or authentication
credentials. (CVE-2011-1926)
Users of cyrus-imapd are advised to upgrade to these updated Linux Distribution Packages,
which contain a backported patch to correct this issue. After installing
the update, cyrus-imapd will be restarted automatically.
Detection Type:
Linux Distribution Package
Solution Type:
Vendor Patch

What's vulnerability management?
Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
