Package        : sympa
CVE ID         : CVE-2020-9369 CVE-2020-10936 CVE-2020-26932 CVE-2020-29668
Debian Bug     : 952428 961491 971904 976020

Several vulnerabilities were discovered in Sympa, a mailing list
manager, which could result in local privilege escalation, denial of
service or unauthorized access via the SOAP API.

Additionally to mitigate CVE-2020-26880 the sympa_newaliases-wrapper is
no longer installed setuid root by default. A new Debconf question is
introduced to allow setuid installations in setups where it is needed.

For the stable distribution (buster), these problems have been fixed in
version 6.2.40~dfsg-1+deb10u1.

We recommend that you upgrade your sympa packages.
