Description Martin Prpič 2016-09-09 13:01:59 UTC
The following flaw was found in PHP:

A memory leak flaw was found in PHP's exif_process_IFD_in_TIFF(). An attacker can leak address and then use it to bypass some protection such as PIE, ASLR, etc.

Upstream bug:

https://bugs.php.net/bug.php?id=72627

Upstream patch:

https://github.com/php/php-src/commit/6dbb1ee46b5f4725cc6519abf91e512a2a10dfed?w=1

Comment 1 Huzaifa S. Sidhpurwala 2016-10-20 05:54:42 UTC
Analysis:

Flaw is a result of a lack of validation when offset data is used from a TIFF image to read from the input stream. This may result in a OOB read. You need an attacker controlled malicious tiff image, which needs to be processed by exif_read_data() to trigger this flaw.
