Debian LTS Advisory DLA-2499-1 [email protected]
https://www.debian.org/lts/security/
December 17, 2020 https://wiki.debian.org/LTS

Package : sympa
Version : 6.2.16~dfsg-3+deb9u5
CVE ID : CVE-2020-29668
Debian Bug : 976020

Sympa, a modern mailing list manager, grants full SOAP API access by
sending invalid string as the cookie value, if the SOAP endpoint was
enabled. An attacker could manipulate the mailing lists, including
subscribing e-mails or getting the list of subscribers.

For Debian 9 stretch, this problem has been fixed in version
6.2.16~dfsg-3+deb9u5.

We recommend that you upgrade your sympa packages.

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