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 a vulnerability as referenced in the ALAS2-2023-2217 advisory.

- An issue was discovered in Oniguruma 6.2.0, as used in Oniguruma-mod in Ruby through 2.4.1 and mbstring in PHP through 7.1.5. A stack out-of-bounds read occurs in match_at() during regular expression searching. A logical error involving order of validation and access in match_at() could result in an out-of-bounds read from a stack buffer. (CVE-2017-9224)

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

Solution

Run 'yum update oniguruma' to update your system.
