DLA 2984-1: condor security update

Debian LTS Advisory DLA-2984-1 Markus Koschany
April 19, 2022

Package : condor
Version : 8.4.11~dfsg.1-1+deb9u2
CVE ID : CVE-2022-26110
Debian Bug : 1008634

Jaime Frey discovered a flaw in HTCondor, a distributed workload management
system. An attacker need only have READ-level authorization to a vulnerable
daemon using the CLAIMTOBE authentication method. This means they are able to
run tools like condor_q or condor_status. Many pools do not restrict who can
issue READ-level commands, and CLAIMTOBE is allowed for READ-level commands in
the default configuration. Thus, it is likely that an attacker could execute
this command remotely from an untrusted network, unless prevented by a firewall
or other network-level access controls.

For Debian 9 stretch, this problem has been fixed in version

We recommend that you upgrade your condor packages.
