DLA-1901-1 dovecot -- LTS security update
- Date Reported:
- 29 Aug 2019
- Affected Packages:
- Security database references:
- In Mitre's CVE dictionary: CVE-2019-11500.
- More information:
Nick 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.
