AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Name of the Vulnerable Software and Affected Versions vim versions prior to 8.0.0378

Description The issue arises from an integer overflow at an unserialize uep memory allocation site. This occurs when vim does not properly validate values for tree length while reading a corrupted undo file, potentially leading to buffer overflows.

Recommendations For versions prior to 8.0.0378, update to version 8.0.0378 or later to resolve the issue. As a temporary workaround, consider avoiding the use of corrupted undo files until a patch is applied. Restrict access to potentially malicious undo files to minimize the risk of exploitation.
