Details

It was discovered that Slurm did not properly handle credential
management, which could allow an unprivileged user to impersonate the
SlurmUser account. An attacker could possibly use this issue to execute
arbitrary code as the root user. (CVE-2022-29500)

It was discovered that Slurm did not properly handle access control when
dealing with RPC traffic through PMI2 and PMIx, which could allow an
unprivileged user to send data to an arbitrary unix socket in the host.
An attacker could possibly use this issue to execute arbitrary code as
the root user. (CVE-2022-29501)

It was discovered that Slurm did not properly handle validation logic when
processing input and output data with the srun client, which could lead to
the interception of process I/O. An attacker could possibly use this issue
to expose sensitive information or execute arbitrary code. This issue only
affected Ubuntu 22.04 LTS. (CVE-2022-29502)
