Synopsis

The specific version of PHP that the system is running is reportedly affected by multiple vulnerabilities.

Description

The specific version of PHP that the system is running is reportedly affected by the following vulnerabilities:

- PHP contains a use-after-free error in ext/session/session.c. The issue is triggered during the handling of var_hash destruction. This may allow a remote attacker to dereference already freed memory and potentially execute arbitrary code. (CVE-2016-6290)

- PHP contains an out-of-bounds read flaw in the exif_process_IFD_in_MAKERNOTE() function in ext/exif/exif.c that may allow a remote attacker to crash a program using the language or potentially disclose memory contents. (CVE-2016-6291)

- PHP contains an overflow condition in the mdecrypt_generic() function in ext/mcrypt/mcrypt.c. The issue is triggered as user-supplied input is not properly validated. This may allow a remote attacker to cause a heap-based buffer overflow, crashing a program using the language or potentially allowing the execution of arbitrary code.

Solution

It has been reported that this has been fixed. Please refer to the product listing for upgraded versions that address this vulnerability.
