Synopsis :

The remote device is affected by a privilege escalation vulnerability.

Description :

According to its self-reported version number, the remote Juniper
Junos device is affected by a heap-based buffer overflow condition in
the sendmsg system call, specifically due to incorrect handling of
arguments in the sockargs() function in sys/kern/uipc_syscalls.c. A
local attacker can exploit this to overwrite large portions of the
kernel memory, resulting in a denial of service condition or the
execution of arbitrary code with elevated privileges.
