CVE-2023-44487 Open this link in a new tabHow to fix?
Upgrade AlmaLinux:9 netstandard-targeting-pack-2.1 to version 0:7.0.112-1.el9_2 or higher.
This issue was patched in ALSA-2023:5749.
NVD Description
Note: Versions mentioned in the description apply only to the upstream netstandard-targeting-pack-2.1 package and not the netstandard-targeting-pack-2.1 package as distributed by AlmaLinux.
See How to fix? for AlmaLinux:9 relevant fixed versions and status.
The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023.
