"In PHP emalloc() function implements the error safe wrapper around malloc(). |
21 |
Unfortunately this function suffers from an integer overflow and |
22 |
considering the fact that emalloc() is used in many places around PHP |
23 |
source code, it may lead to many serious security issues." |
24 |
|
25 |
"The function str_repeat(string input, int multiplier) returns input |
26 |
repeated multiplier times. |
27 |
|
28 |
The implementation of this function suffers from a simple integer overflow |
29 |
caused by a very long second argument and could allow a local/remote |
30 |
attacker in the worst case to gain control over the web server." |
31 |
|
32 |
"The function array_pad(array input, int pad_size, mixed pad_value) returns |
33 |
a copy of the input padded to size specified by pad_size with pad_value. |
