loader, making it possible to load attacker-controlled shared objects |
47 |
during execution of setuid/setgid programs to escalate privileges. |
48 |
|
49 |
A context-dependent attacker could trigger various vulnerabilities in |
50 |
GNU C Library, including a buffer overflow, leading to execution of |
51 |
arbitrary code or a Denial of Service. |
52 |
|
53 |
Workaround |
