Amazon Linux AMI : e2fsprogs (ALAS-2020-1459) (deprecated)

medium Nessus Plugin ID 144471

Language:

Synopsis

This plugin has been deprecated.

Description

The version of tested product installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2020-1459 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)

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

This plugin has been deprecated due to Amazon pulling the previously published advisory.
