Debian LTS Advisory DLA-3664-1 [email protected]

Package : symfony
Version : 3.4.22+dfsg-2+deb10u3
CVE ID : CVE-2023-46734
Debian Bug : 1055774

Pierre Rudloff discovered a potential XSS vulnerability in Symfony, a PHP
framework. Some Twig filters in CodeExtension use is_safe=html but do not
actually ensure their input is safe. Symfony now escapes the output of the
affected filters.

For Debian 10 buster, this problem has been fixed in version
3.4.22+dfsg-2+deb10u3.

We recommend that you upgrade your symfony packages.

For the detailed security status of symfony please refer to
its security tracker page at:
