Debian 9858 Published by

Updated Squirrelmail packages has been released for Debian GNU/Linux 8 LTS



Package : squirrelmail
Version : 2:1.4.23~svn20120406-2+deb8u4
CVE ID : CVE-2019-12970

A XSS vulnerability was discovered in SquirrelMail. Due to improper
handling of RCDATA and RAWTEXT type elements, the built-in
sanitization mechanism can be bypassed. Malicious script content from
HTML e-mails can be executed within the application context via
crafted use of (for example) a NOEMBED, NOFRAMES, NOSCRIPT, or
TEXTAREA element.

For Debian 8 "Jessie", this problem has been fixed in version
2:1.4.23~svn20120406-2+deb8u4.

We recommend that you upgrade your squirrelmail packages.
