Publication date: 08 Jan 2021
URL: https://advisories.mageia.org/MGASA-2021-0010.html
Type: security
Affected Mageia releases: 7
CVE: CVE-2019-12970

XSS was discovered in SquirrelMail through 1.4.22. Due to improper handling of
RCDATA and RAWTEXT type elements, the built-in sanitization mechanism can be
bypassed. Malicious script content from HTML e-mail can be executed within the
application context via crafted use of (for example) a NOEMBED, NOFRAMES,
NOSCRIPT, or TEXTAREA element ().

An unsafe use of unserialize() in compose.php has also been fixed.
