------------------------------------------------------------------------- Debian LTS Advisory DLA-4169-1 debian-lts@lists.debian.org https://www.debian.org/lts/security/ Guilhem Moulin May 17, 2025 https://wiki.debian.org/LTS ------------------------------------------------------------------------- Package : dropbear Version : 2020.81-3+deb11u3 CVE ID : CVE-2025-47203 Marcin Nowak discovered that dbclient(1) hostname arguments with a comma (for multihop) are passed to the shell which could result in running arbitrary shell commands locally. That could be a security issue in situations where dbclient(1) is passed untrusted hostname arguments. For Debian 11 bullseye, this problem has been fixed in version 2020.81-3+deb11u3. We recommend that you upgrade your dropbear packages. For the detailed security status of dropbear please refer to its security tracker page at: https://security-tracker.debian.org/tracker/dropbear 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
