Description

This security bulletin contains information about 2 secuirty vulnerabilities.


1) Integer overflow (CVE-ID: CVE-2016-3078)

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

Multiple integer overflows in php_zip.c in the zip extension in PHP before 7.0.6 allow remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted call to (1) getFromIndex or (2) getFromName in the ZipArchive class.


2) Buffer overflow (CVE-ID: CVE-2016-4544)

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

The exif_process_TIFF_in_JPEG function in ext/exif/exif.c in PHP before 5.5.35, 5.6.x before 5.6.21, and 7.x before 7.0.6 does not validate TIFF start data, which allows remote attackers to cause a denial of service (out-of-bounds read) or possibly have unspecified other impact via crafted header data.
