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.

SynopsisThe remote Debian host is missing a security update.
DescriptionNick Roessler and Rafi Rubin discovered that the IMAP and ManageSieve protocol parsers in the Dovecot email server do not properly validate input (both pre- and post-login). A remote attacker can take advantage of this flaw to trigger out of bounds heap memory writes, leading to information leaks or potentially the execution of arbitrary code.
For Debian 8 'Jessie', this problem has been fixed in version 1:2.2.13-12~deb8u7.
We recommend that you upgrade your dovecot packages.
