Debian DSA-3783-1 Critical: PHP5 DoS And Code Execution Risks

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.
