Package        : php5
CVE ID         : CVE-2016-10158 CVE-2016-10159 CVE-2016-10160
                 CVE-2016-10161

Several issues have been discovered in PHP, a widely-used open source
general-purpose scripting language.

CVE-2016-10158

    Loading a TIFF or JPEG malicious file can lead to a Denial-of-Service
    attack when the EXIF header is being parsed.

CVE-2016-10159

    Loading a malicious phar archive can cause an extensive memory
    allocation, leading to a Denial-of-Service attack on 32 bit
    computers.

CVE-2016-10160

    An attacker might remotely execute arbitrary code using a malicious
    phar archive. This is the consequence of an off-by-one memory
    corruption.

CVE-2016-10161

    An attacker with control of the unserialize() function argument can
    cause an out-of-bounce read. This could lead to a Denial-of-Service
    attack or a remote code execution.

For the stable distribution (jessie), these problems have been fixed in
version 5.6.30+dfsg-0+deb8u1.

We recommend that you upgrade your php5 packages.
