Juniper Junos sendmsg Local Privilege Escalation (JSA10797)

High Nessus Plugin ID 102072


The remote device is affected by a privilege escalation vulnerability.


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.


Upgrade to the relevant Junos software release referenced in Juniper security advisory JSA10797.
