Affected Packages:
Security database references:
In Mitre's CVE dictionary: CVE-2019-12970.
More information:

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.
