Amazon Linux 2 : php (ALAS-2024-2520)

critical Nessus Plugin ID 193527

Language:

Synopsis

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

Description

The version of php installed on the remote host is prior to 5.4.16-46. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2024-2520 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 mbc_enc_len() during regular expression searching.
 Invalid handling of reg->dmin in forward_search_range() could result in an invalid pointer dereference, as an out-of-bounds read from a stack buffer. (CVE-2017-9227)

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

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 php' to update your system.
