Package : dovecot
Debian Bug : 1115474 1115964
A flaw with the authentication cache management was discovered in the
Dovecot email server, which could result in users being logged in as the
wrong user in certain configurations.
For the stable distribution (trixie), this problem has been fixed in
version 1:2.4.1+dfsg1-6+deb13u1.
We recommend that you upgrade your dovecot packages.
