------------------------------------------------------------------------- Debian LTS Advisory DLA-4647-1 debian-lts@lists.debian.org https://www.debian.org/lts/security/ Daniel Leidert June 25, 2026 https://wiki.debian.org/LTS ------------------------------------------------------------------------- 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 Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: https://wiki.debian.org/LTS
