- Security database references:
- In Mitre's CVE dictionary: CVE-2016-10158, CVE-2016-10159, CVE-2016-10160, CVE-2016-10161.
- More information:
Several issues have been discovered in PHP, a widely-used open source general-purpose scripting language.
Loading a TIFF or JPEG malicious file can lead to a Denial-of-Service attack when the EXIF header is being parsed.
Loading a malicious phar archive can cause an extensive memory allocation, leading to a Denial-of-Service attack on 32 bit computers.
An attacker might remotely execute arbitrary code using a malicious phar archive. This is the consequence of an off-by-one memory corruption.
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.
