The AlmaLinux security team deemed this advisory irrelevant for AlmaLinux:10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream xxd package and not the xxd package as distributed by AlmaLinux.
Vim is an open source, command line text editor. Versions prior to 9.2.0077 have a heap-buffer-overflow and a segmentation fault (SEGV) exist in Vim's swap file recovery logic. Both are caused by unvalidated fields read from crafted pointer blocks within a swap file. Version 9.2.0077 fixes the issue.
