Amazon Linux 2 : vim (ALAS-2023-2005)

medium Nessus Plugin ID 173910

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2023-2005 advisory.

 A heap-based buffer overflow vulnerability was found in GitHub repository vim/vim prior to 9.0.1376 in Vim's utf_ptr2char() function of the src/mbyte.c file. This flaw occurs because there is access to invalid memory with put in visual block mode. An attacker can trick a user into opening a specially crafted file, triggering an out-of-bounds read that causes an application to crash, leading to a denial of service.
 (CVE-2023-1170)

 Incorrect Calculation of Buffer Size in GitHub repository vim/vim prior to 9.0.1378. (CVE-2023-1175)

 NULL Pointer Dereference in GitHub repository vim/vim prior to 9.0.1392. (CVE-2023-1264)

 NULL Pointer Dereference in GitHub repository vim/vim prior to 9.0.1402. (CVE-2023-1355)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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

Solution

Run 'yum update vim' to update your system.
