------------------------------------------------------------------------- Debian LTS Advisory DLA-4338-1 [email protected] https://www.debian.org/lts/security/ Andreas Henriksson October 18, 2025 https://wiki.debian.org/LTS
-------------------------------------------------------------------------

Package : pgagent Version : 4.0.0-8+deb11u1 CVE ID : CVE-2025-0218 Debian Bug : 1092677

When batch jobs are executed by pgAgent, a script is created in a temporary directory and then executed. In versions of pgAgent prior to 4.2.3, an insufficiently seeded random number generator is used when generating the directory name, leading to the possibility for a local attacker to pre-create the directory and thus prevent pgAgent from executing jobs, disrupting scheduled tasks.

For Debian 11 bullseye, this problem has been fixed in version 4.0.0-8+deb11u1.

We recommend that you upgrade your pgagent packages.

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