    Package        : dovecot
    CVE ID         : CVE-2020-12100 CVE-2020-12673 CVE-2020-12674
    
    Several vulnerabilities have been discovered in the Dovecot email
    server.
    
    CVE-2020-12100
    
        Receiving mail with deeply nested MIME parts leads to resource
        exhaustion as Dovecot attempts to parse it.
    
    CVE-2020-12673
    
        Dovecot's NTLM implementation does not correctly check message
        buffer size, which leads to a crash when reading past allocation.
    
    CVE-2020-12674
    
        Dovecot's RPA mechanism implementation accepts zero-length message,
        which leads to assert-crash later on.
    
    For the stable distribution (buster), these problems have been fixed in
    version 1:2.3.4.1-5+deb10u3.
    
    We recommend that you upgrade your dovecot packages.
