file(1) AFCTR tool read() buffer overflow
| file-afctr-read-bo (11469) |  High Risk |
Description:
file(1) is vulnerable to a stack-based buffer overflow in the Automatic File Content Type Recognition Tool (AFCTR tool) , caused by improper bounds checking of user-supplied input that is passed to the read() function. By creating a specially-crafted file and setting the sh_addr variable to more than 32 bytes, a local attacker could overflow a buffer and execute arbitrary code on the system with privileges of the file(1) user, once the victim opens the file using the AFCTR tool.
Consequences:
Gain Privileges
