PatchTheCVECVE-2023-1326: A privilege escalation attack was found in apport-cli 2.26.0 and earlier which is similar to CVE-2023-26604
CVE-2023-1326 is a high-severity flaw (CVSS 7.7) affecting apport, ubuntu linux. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
A privilege escalation attack was found in apport-cli 2.26.0 and earlier which is similar to CVE-2023-26604. If a system is specially configured to allow unprivileged users to run sudo apport-cli, less is configured as the pager, and the terminal size can be set: a local attacker can escalate privilege. It is extremely unlikely that a system administrator would configure sudo to allow unprivileged users to perform this class of exploit.
