Amazon Linux AMI : php55 (ALAS-2015-507)

high Nessus Plugin ID 82835

Language:

Synopsis

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

Description

A use-after-free flaw was found in the way PHP's unserialize() function processed data. If a remote attacker was able to pass crafted input to PHP's unserialize() function, they could cause the PHP interpreter to crash or, possibly, execute arbitrary code.
(CVE-2015-0231)

An integer overflow flaw, leading to a heap-based buffer overflow, was found in the way libzip, which is also embedded in PHP, processed certain ZIP archives. If an attacker were able to supply a specially crafted ZIP archive to an application using libzip, it could cause the application to crash or, possibly, execute arbitrary code.
(CVE-2015-2331)

Integer overflow in the regcomp implementation in the Henry Spencer BSD regex library (aka rxspencer) alpha3.8.g5 on 32-bit platforms, as used in NetBSD through 6.1.5 and other products, might allow context-dependent attackers to execute arbitrary code via a large regular expression that leads to a heap-based buffer overflow.
(CVE-2015-2305)

Solution

Run 'yum update php55' to update your system.
