Closes: 1123069
Changes:
dropbear (2025.89-1~deb13u1) trixie-security; urgency=high
.
* New upstream security and bugfix release (closes: #1123069).
+ Fix CVE-2025-14282: Privilege escalation via unix stream forwarding in
Dropbear server. Other programs on a system may authenticate unix
sockets via SO_PEERCRED, which would be root user for Dropbear forwarded
connections, allowing root privilege escalation.
+ The server now drops privileges of the dropbear process after
authentication.
+ Remote server TCP socket forwarding will now use OS privileged port
restrictions rather than having a fixed "allow >=1024 for non-root"
rule.
+ Unix stream sockets are now disallowed when a forced command is used,
either with authorized_key restrictions or "dropbear -c command".
* DEP-8: Add "Depends: e2fsprogs" to remote-unlocking test.
