Pan .nzb file buffer overflow
| pan-nzb-bo (42750) |  High Risk |
Description:
Pan is vulnerable to a heap-based buffer overflow, caused by improper bounds checking when parsing malicious files. By persuading a victim to open a specially-crafted .nzb file, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
