Debian Security Advisory DSA-4825-1 [email protected]

Package : dovecot
CVE ID : CVE-2020-24386 CVE-2020-25275
Several vulnerabilities have been discovered in the Dovecot email
server.
CVE-2020-24386
When imap hibernation is active, an attacker (with valid credentials
to access the mail server) can cause Dovecot to discover file system
directory structures and access other users' emails via specially
crafted commands.
CVE-2020-25275
Innokentii Sennovskiy reported that the mail delivery and parsing in
Dovecot can crash when the 10000th MIME part is message/rfc822 (or
if the parent was multipart/digest). This flaw was introduced by
earlier changes addressing CVE-2020-12100.
For the stable distribution (buster), these problems have been fixed in
version 1:2.3.4.1-5+deb10u5.
We recommend that you upgrade your dovecot packages.
For the detailed security status of dovecot please refer to its security
tracker page at:
https://security-tracker.debian.org/tracker/dovecot
