Cscope cscope.lists buffer overflow
| cscope-cscopelists-bo (28545) |  High Risk |
Description:
Cscope is vulnerable to a stack-based buffer overflow, caused by improper bounds checking when parsing file lists or expanding environment variables. By sending a specially-crafted cscope.lists file, a remote attacker could overflow a buffer and execute arbitrary code on the system.
