GNU's tar and cpio utilities are prone to a denial-of-service vulnerability because of insecure use of the 'alloca()' function.
|
|
|
|
Successfully exploiting this issue allows attackers to crash the affected utilities and possibly to execute code, but this has not been confirmed.
|
|
|
|
GNU tar and cpio utilities share the same vulnerable code and are both affected. Other utilities sharing this code may also be affected.
