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.
Sympa before 6.2.59b.2 allows remote attackers to obtain full SOAP API access by sending any arbitrary string (except one from an expired cookie) as the cookie value to authenticateAndRun.
debian/sympa.postinst for the Debian Sympa package before 6.2.40~dfsg-7 uses mode 4755 for sympanewaliases-wrapper, whereas the intended permissions are mode 4750 (for access by the sympa group)
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 sympanewaliases-wrapper executable.

Sympa 6.2.38 through 6.2.52 allows remote attackers to cause a denial of service (disk consumption from temporary files, and a flood of notifications to listmasters) via a series of requests with malformed parameters.

The newsletter posting area in the web interface in Sympa 6.0.x before 6.0.10 and 6.1.x before 6.1.24 allows remote attackers to read arbitrary files via unspecified vectors.
The archive management (arcmanage) page in wwsympa/wwsympa.fcgi.in in Sympa before 6.1.11 does not check permissions, which allows remote attackers to list, read, and delete arbitrary list archives via vectors related to the (1) doarcmanage, (2) doarcdownload, or (3) doarcdelete functions.
sympa.pl in sympa 5.3.4 allows local users to overwrite arbitrary files via a symlink attack on the /tmp/sympaaliases.$$ temporary file. NOTE: wwsympa.fcgi was also reported, but the issue occurred in a dead function, so it is not a vulnerability.
Sympa before 5.4 allows remote attackers to cause a denial of service (daemon crash) via an e-mail message with a malformed value of the Content-Type header and unspecified other headers. NOTE: some of these details are obtained from third party information.
Buffer overflow in queue.c in a support script for sympa 3.3.3, when running setuid, allows local users to execute arbitrary code.
Cross-site scripting (XSS) vulnerability in the create list option in Sympa 4.1.x and earlier allows remote authenticated users to inject arbitrary web script or HTML via the description field.
