Samba QFILEPATHINFO buffer overflow
| samba-qfilepathinfo-bo (18070) |
Description:
Samba is vulnerable to a buffer overflow in the QFILEPATHINFO request handler. A remote authenticated attacker could send a specially-crafted TRANSACT2_QFILEPATHINFO request for a specific file name containing unicode characters to overflow a buffer and execute arbitrary code on the system.
