Vulnerability Assessment Details
Detailed Explanation for this Vulnerability Assessment
These remote packages are missing security patches :
Stefan Esser reported several buffer overflows in PHP's variable unserializing
handling. These could permit a possible hacker to execute arbitrary code on the server
with the PHP interpreter's rights by sending specially crafted input
strings (form data, cookie values, and similar).
Additionally, Ilia Alshanetsky discovered a buffer overflow in the
exif_read_data() function. Attackers could execute arbitrary code on the server
by sending a JPEG image with a very long "sectionname" value to PHP
applications that support image uploads.
