|
A buffer overflow vulnerability exists in the htdigest utility included with Apache. The vulnerability is due to improper bounds checking when copying user-supplied realm data into local buffers.
|
|
|
|
By supplying an overly long realm value to the command line options of htdigest, it is possible to trigger an overflow condition. This may cause memory to be corrupted with attacker-specified values.
|
|
|
|
This issue could be exploited by a remote attacker; potentially resulting in the execution of arbitrary system commands within the context of the web server process.
