Arch Linux Security Advisory ASA-201504-14
Date : 2015-04-17
CVE-ID : CVE-2015-1351 CVE-2015-1352 CVE-2015-2783
Package : php
Type : multiple issues
Remote : Yes
Link : https://wiki.archlinux.org/index.php/CVE
The package php before version 5.6.8-1 is vulnerable to denial of
service and information disclosure.
Upgrade to 5.6.8-1.
# pacman -Syu "php>=5.6.8-1"
The problems have been fixed upstream in version 5.6.8.
- CVE-2015-1351 (denial of service)
Use-after-free vulnerability in the _zend_shared_memdup function in
zend_shared_alloc.c in the OPcache extension allows remote attackers to
cause a denial of service or possibly have unspecified other impact via
- CVE-2015-1352 (denial of service)
The build_tablename function in pgsql.c in the PostgreSQL (aka pgsql)
extension does not validate token extraction for table names, which
allows remote attackers to cause a denial of service (NULL pointer
dereference and application crash) via a crafted name.
- CVE-2015-2783 (out-of-bounds read)
The vulnerability can be triggered when parsing a PHAR file at
phar.c:623. The "buf_len" is obtained from the phar file and passed into
php_var_unserialize() as the max argument. Under normal
php_var_unserialize() circumstances, YYCURSOR will always be <= max.
This however can be bypassed when processing a malform phar with a
buf_len that is shorter then the string to be unserialized resulting in
a memory info leak.
A remote attacker is able to perform denial of service attacks via
multiple vectors or use a crafted PHAR file to read beyond a buffer
resulting in information disclosure.
