CVE-2017-2344

Vulnerability Summary

A routine within an internal Junos OS sockets library is vulnerable to a buffer overflow. Malicious exploitation of this issue may lead to a denial of service (kernel panic) or be leveraged as a privilege escalation through local code execution. The routines are only accessible via programs running on the device itself, and veriexec restricts arbitrary programs from running on Junos OS. There are no known exploit vectors utilizing signed binaries shipped with Junos OS itself. Affected releases are Juniper Networks Junos OS 12.1X46 before 12.1X46-D67; 12.3X48 before 12.3X48-D51, 12.3X48-D55; 13.3 before 13.3R10-S2; 14.1 before 14.1R2-S10, 14.1R8-S4, 14.1R9; 14.1X50 before 14.1X50-D185; 14.1X53 before 14.1X53-D122, 14.1X53-D45, 14.1X53-D50; 14.2 before 14.2R4-S9, 14.2R7-S7, 14.2R8; 15.1 before 15.1F2-S18, 15.1F6-S7, 15.1R4-S8, 15.1R5-S5, 15.1R6-S1, 15.1R7; 15.1X49 before 15.1X49-D100; 15.1X53 before 15.1X53-D231, 15.1X53-D47, 15.1X53-D48, 15.1X53-D57, 15.1X53-D64, 15.1X53-D70; 16.1 before 16.1R3-S4, 16.1R4-S3, 16.1R4-S4, 16.1R5; 16.2 before 16.2R2; 17.1 before 17.1R1-S3, 17.1R2; 17.2 before 17.2R1-S1, 17.2R2; 17.2X75 before 17.2X75-D30.
