Description

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.
