Synopsis
The version of PHP running on the remote web server is affected by multiple vulnerabilities.Description
According to its banner, the version of PHP running on the remote web server is 5.5.x prior to 5.5.35. It is, therefore, affected by multiple vulnerabilities :- A signedness error exists in the GD Graphics library within file gd_gd2.c due to improper validation of user-supplied input when handling compressed GD2 data.
An unauthenticated, remote attacker can exploit this to cause a heap-based buffer overflow, resulting in a denial of service condition or the execution of arbitrary code. (CVE-2016-3074)
- An out-of-bounds read error exists within file ext/intl/grapheme/grapheme_string.c when handling negative offsets in the zif_grapheme_stripos() function.
An unauthenticated, remote attacker can exploit this to cause a denial of service condition or disclose memory contents.
- An out-of-bounds read error exists in the php_str2num() function within file ext/bcmath/bcmath.c when handling negative scales. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or the disclosure of memory contents.
- An out-of-bounds read error exists in the exif_read_data() function within file ext/exif/exif.c when handling exif headers. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or the disclosure of memory contents.
- A flaw exists in the xml_parse_into_struct() function within file ext/xml/xml.c when handling specially crafted XML contents. An unauthenticated, remote attacker can exploit this to cause a denial of service condition.
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
