There are 2 open security issues in bullseye.
2 issues left for the package maintainer to handle:
- CVE-2020-26880:
(postponed; to be fixed through a stable update)
Sympa through 6.2.57b.2 allows a local privilege escalation from the sympa user account to full root access by modifying the sympa.conf configuration file (which is owned by sympa) and parsing it through the setuid sympa_newaliases-wrapper executable.
- CVE-2021-46900:
(needs triaging)
Sympa before 6.2.62 relies on a cookie parameter for certain security objectives, but does not ensure that this parameter exists and has an unpredictable value. Specifically, the cookie parameter is both a salt for stored passwords and an XSS protection mechanism.
You can find information about how to handle these issues in the security team's documentation.
