PyCrypto ARC2 buffer overflow
| pycrypto-arc2module-bo (48617) |  High Risk |
Description:
PyCrypto is vulnerable to a buffer overflow, caused by improper bounds checking by the ARC2 module. By sending a specially-crafted request, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
