| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2012-05-11 | CVE-2012-1823 | sapi/cgi/cgi_main.c in PHP before 5.3.12 and 5.4.x before 5.4.2, when configured as a CGI script (aka php-cgi), does not properly handle query strings that lack an = (equals sign) character, which allows remote attackers to execute arbitrary code by placing command-line options in the query string, related to lack of skipping a certain php_getopt for the 'd' case. | 9.8 |
| 2010-05-07 | CVE-2010-1866 | Integer Overflow or Wraparound vulnerability in multiple products The dechunk filter in PHP 5.3 through 5.3.2, when decoding an HTTP chunked encoding stream, allows context-dependent attackers to cause a denial of service (crash) and possibly trigger memory corruption via a negative chunk size, which bypasses a signed comparison, related to an integer overflow in the chunk size decoder. | 9.8 |
| 2008-05-07 | CVE-2008-2108 | Insufficient Entropy vulnerability in multiple products The GENERATE_SEED macro in PHP 4.x before 4.4.8 and 5.x before 5.2.5, when running on 64-bit systems, performs a multiplication that generates a portion of zero bits during conversion due to insufficient precision, which produces 24 bits of entropy and simplifies brute force attacks against protection mechanisms that use the rand and mt_rand functions. | 9.8 |
| 2008-05-05 | CVE-2008-0599 | Incorrect Calculation of Buffer Size vulnerability in multiple products The init_request_info function in sapi/cgi/cgi_main.c in PHP before 5.2.6 does not properly consider operator precedence when calculating the length of PATH_TRANSLATED, which might allow remote attackers to execute arbitrary code via a crafted URI. | 9.8 |
