GNU glibc is prone to a stack-corruption vulnerability.
|
|
|
|
An attacker can exploit this issue to execute arbitrary machine code in the context of the application that uses the affected library. Failed exploit attempts will likely crash the application.
|
|
|
|
GNU glibc versions prior to 2.12.2 are vulnerable. */
