Package        : php-horde-gollem
Version        : 3.0.3-2+deb8u1
CVE ID         : CVE-2020-8034
Debian Bug     : 961649


Gollem, as used in Horde Groupware Webmail Edition and other products,
had been affected by a reflected Cross-Site Scripting (XSS) vulnerability
via the HTTP GET dir parameter in the browser functionality, affecting
breadcrumb output. An attacker could have obtained access to a victim's
webmail account by making them visit a malicious URL.

For Debian 8 "Jessie", this problem has been fixed in version
3.0.3-2+deb8u1.

We recommend that you upgrade your php-horde-gollem packages.
