Amazon Linux 2 : oniguruma (ALAS-2020-1380)

critical Nessus Plugin ID 132735

Language:

Synopsis

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

Description

The version of oniguruma installed on the remote host is prior to 5.9.6-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2020-1380 advisory.

Oniguruma before 6.9.3 allows Stack Exhaustion in regcomp.c because of recursion in regparse.c.
(CVE-2019-16163)

Oniguruma through 6.9.3, as used in PHP 7.3.x and other products, has a heap-based buffer over-read in str_lower_case_match in regexec.c.(CVE-2019-19246)

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 oniguruma' to update your system.
