    Package : dovecot
    CVE ID : CVE-2019-11500

    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 the oldstable distribution (stretch), this problem has been fixed
    in version 1:2.2.27-3+deb9u5.

    For the stable distribution (buster), this problem has been fixed in
    version 1:2.3.4.1-5+deb10u1.

    We recommend that you upgrade your dovecot packages.

    For the detailed security status of dovecot please refer to its security tracker page at:
