usbmuxd libusbmuxd.c buffer overflow

usbmuxd-libusbmuxd-bo (72546) The risk level is classified as HighHigh Risk

Description:

usbmuxd is vulnerable to a heap-based buffer overflow, caused by improper bounds checking by receive_packet() function in libusbmuxd.c when processing property list. By sending a specially-crafted request containing an overly long SerialNumber field, a local attacker connected to a malicious USB device could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
