CentOS 9 : qemu-kvm-6.2.0-7.el9

high Nessus Plugin ID 191343

Synopsis

The remote CentOS host is missing one or more security updates for qemu-guest-agent.

Description

The remote CentOS Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the qemu-kvm-6.2.0-7.el9 build changelog.

 - The inode_init_owner function in fs/inode.c in the Linux kernel through 3.16 allows local users to create files with an unintended group ownership, in a scenario where a directory is SGID to a certain group and is writable by a user who is not a member of that group. Here, the non-member can trigger creation of a plain file whose group ownership is that group. The intended behavior was that the non-member can trigger creation of a directory (but not a plain file) whose group ownership is that group. The non-member can escalate privileges by making the plain file executable and SGID. (CVE-2018-13405)

 - potential privilege escalation via CVE-2018-13405 [rhel-9.0]) (CVE-2022-0358)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the CentOS 9 Stream qemu-guest-agent package.
