Package        : yelp
Version        : 3.38.3-1+deb11u2
CVE ID         : not assigned
Debian Bug     : 1136299

A vulnerability was discovered in yelp, the GNOME help browser, that
allows a crafted help document to read files accessible to the user and
exfiltrate them to a remote server through resources loaded by the
embedded web view. When yelp is launched from a sandboxed application
(for example via the Flatpak OpenURI portal), this also enables a
sandbox escape.

For Debian 11 bullseye, this problem has been fixed in version
3.38.3-1+deb11u2.

We recommend that you upgrade your yelp packages.

For the detailed security status of yelp please refer to
its security tracker page at:
https://security-tracker.debian.org/tracker/yelp
