2019-01 Security Bulletin: Junos OS: Kernel crash after processing specific
incoming packet to the out of band management interface (CVE-2019-0011)
[JSA10911]
Product Affected:
This issue affects Junos OS 17.2, 17.2X75, 17.3, 17.4, 18.1.
Problem:
The Junos OS kernel crashes after processing a specific incoming packet to the
out of band management interface (such as fxp0, me0, em0, vme0) destined for
another address.
By continuously sending this type of packet, an attacker can repeatedly crash
the kernel causing a sustained Denial of Service.
Affected releases are Juniper Networks Junos OS:
17.2 versions prior to 17.2R1-S7, 17.2R3;
17.3 versions prior to 17.3R3-S3;
17.4 versions prior to 17.4R1-S4, 17.4R2;
17.2X75 versions prior to 17.2X75-D110;
18.1 versions prior to 18.1R2.
Juniper SIRT is not aware of any malicious exploitation of this vulnerability.
This issue was seen during production usage.
This issue has been assigned CVE-2019-0011.
Solution:
The following software releases have been updated to resolve this specific
issue: Junos OS 17.2R1-S7, 17.2R3, 17.2X75-D110, 17.3R3-S3, 17.4R1-S4, 17.4R2,
18.1R2, 18.2R1, 18.2X75-D5, and all subsequent releases.
Note: Juniper SIRT's policy is not to evaluate releases which are beyond End of
Engineering (EOE) or End of Life (EOL).
Workaround:
Apply a firewall filter on the management interface which permits only the
necessary traffic on management interface to the device's local address, such
as SNMP, SSH, or other management traffic and drops everything else.
Implementation:
Software Releases, patches and updates are available at
https://www.juniper.net/support/downloads/.
Modification History:
2019-01-09: Initial Publication.
2019-01-10: minor edit on the solution section.

2019-01 Security Bulletin: Junos OS: rpd crash on VPLS PE upon receipt of
specific BGP message (CVE-2019-0012)
[JSA10912]
Product Affected:
This issue affects Junos OS 12.1X46, 12.3, 12.3X48, 14.1X53, 15.1, 15.1X49,
15.1X53, 16.1, 16.2, 17.1, 17.2, 17.3, 17.4, 18.1.
Problem:
A Denial of Service (DoS) vulnerability in BGP in Juniper Networks Junos OS
configured as a VPLS PE allows an attacker to craft a specific BGP message to
cause the routing protocol daemon (rpd) process to crash and restart. While rpd
restarts after a crash, repeated crashes can result in an extended DoS
condition.
This issue only affects PE routers configured with BGP Auto discovery for LDP
VPLS. Other BGP configurations are unaffected by this vulnerability.
Affected releases are Juniper Networks Junos OS:
12.1X46 versions prior to 12.1X46-D81;
12.3 versions prior to 12.3R12-S12;
12.3X48 versions prior to 12.3X48-D76;
14.1X53 versions prior to 14.1X53-D48;
15.1 versions prior to 15.1F6-S12, 15.1R7-S2;
15.1X49 versions prior to 15.1X49-D150;
15.1X53 versions prior to 15.1X53-D235, 15.1X53-D495, 15.1X53-D590, 15.1X53-D68;
16.1 versions prior to 16.1R3-S10, 16.1R4-S12, 16.1R6-S6, 16.1R7-S1;
16.2 versions prior to 16.2R2-S7;
17.1 versions prior to 17.1R2-S9, 17.1R3;
17.2 versions prior to 17.2R1-S7, 17.2R2-S6, 17.2R3;
17.3 versions prior to 17.3R2-S4, 17.3R3;
17.4 versions prior to 17.4R1-S5, 17.4R2;
18.1 versions prior to 18.1R2-S3, 18.1R3.
This issue only occurs when BGP Auto discovery for LDP VPLS is configured:
set protocols bgp group <name> family l2vpn auto-discovery-only
set routing-instances <name> instance-type vpls
set routing-instances <name> l2vpn-id l2vpn-id:<id>
Juniper SIRT is not aware of any malicious exploitation of this vulnerability.
This issue was seen during production usage.
This issue has been assigned CVE-2019-0012.
Solution:

issue: Junos OS 12.1X46-D81, 12.3R12-S12, 12.3X48-D76, 12.3X48-D80, 15.1F6-S12,
15.1R7-S2, 15.1X49-D150, 15.1X53-D235, 15.1X53-D495, 15.1X53-D590, 15.1X53-D68,
16.1R3-S10, 16.1R4-S12, 16.1R6-S6, 16.1R7-S1, 16.2R2-S7, 17.1R2-S9, 17.1R3,
17.2R1-S7, 17.2R2-S6, 17.2R3, 17.3R2-S4, 17.3R3, 17.4R1-S5, 17.4R2, 18.1R2-S3,
18.1R3, 18.2R1, 18.2X75-D10, and all subsequent releases.

2019-01 Security Bulletin: Junos OS: RPD crash upon receipt of malformed PIM
packet (CVE-2019-0013)
