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

critical Nessus Plugin ID 193527

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)

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.
