Cscope find.c buffer overflow
| cscope-findc-bo (50366) |  High Risk |
Description:
Cscope is vulnerable to a stack-based buffer overflow, caused by improper bounds checking by the find.c script. By sending a specially-crafted file containing an overly long function, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
