More information:

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.
