Amazon Linux AMI : e2fsprogs (ALAS-2021-1458)

medium Nessus Plugin ID 144997

Language:

Synopsis

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

Description

The version of e2fsprogs installed on the remote host is prior to 1.43.5-2.44. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2021-1458 advisory.

 An exploitable code execution vulnerability exists in the quota file functionality of E2fsprogs 1.45.3. A specially crafted ext4 partition can cause an out-of-bounds write on the heap, resulting in code execution. An attacker can corrupt a partition to trigger this vulnerability. (CVE-2019-5094)

 A code execution vulnerability exists in the directory rehashing functionality of E2fsprogs e2fsck 1.45.4.
 A specially crafted ext4 directory can cause an out-of-bounds write on the stack, resulting in code execution. An attacker can corrupt a partition to trigger this vulnerability. (CVE-2019-5188)

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 e2fsprogs' to update your system.
