Package : yelp CVE ID :
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 the oldstable distribution (bookworm), this problem has been fixed in version 42.2-1+deb12u2.

For the stable distribution (trixie), this problem has been fixed in version 42.2-4+deb13u1.

We recommend that you upgrade your yelp packages.

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