Stack overflow

Insufficient validation of environment variables in the telnet client supplied in Junos OS can lead to stack-based buffer overflows, which can be exploited to bypass veriexec restrictions on Junos OS. A stack-based overflow is present in the handling of environment variables when connecting via t...

Design/Logic Flaw

On Junos devices with the BGP graceful restart helper mode enabled or the BGP graceful restart mechanism enabled, a certain sequence of BGP session restart on a remote peer that has the graceful restart mechanism enabled may cause the local routing protocol daemon RPD process to crash and restart...

Design/Logic Flaw

The srxpfe process may crash on SRX Series services gateways when the UTM module processes a specific fragmented HTTP packet. The packet is misinterpreted as a regular TCP packet which causes the processor to crash. This issue affects all SRX Series platforms that support URL-Filtering and have...

CVE-2019-0046 Junos OS: EX4300 Series: Denial of Service upon receipt of large number of specific valid packets on management interface.

A vulnerability in the pfe-chassisd Chassis Manager CMLC daemon of Juniper Networks Junos OS allows an attacker to cause a Denial of Service DoS to the EX4300 when specific valid broadcast packets create a broadcast storm condition when received on the me0 interface of the EX4300 Series device. A...

CVE-2019-0053

The CVE-2019-0053 entry concerns the inetutils Telnet client in Junos OS, where environment-variable handling is insufficiently validated, causing a stack-based buffer overflow. This vulnerability is local to the Telnet client used from the CLI or shell, with inbound Telnet services unaffected. A...

CVE-2019-0052

The CVE-2019-0052 issue affects Juniper Networks Junos OS on SRX Series gateways, where the srxpfe process crashes when the UTM/JSF module processes a specific fragmented HTTP packet. The packet is misinterpreted as a normal TCP packet, causing a processor crash. Affected releases cover multiple ...

CVE-2019-0052 SRX Series: srxpfe process crash while JSF/UTM module parses specific HTTP packets

The srxpfe process may crash on SRX Series services gateways when the UTM module processes a specific fragmented HTTP packet. The packet is misinterpreted as a regular TCP packet which causes the processor to crash. This issue affects all SRX Series platforms that support URL-Filtering and have...

CVE-2019-0046

Summary: CVE-2019-0046 affects Juniper Networks Junos OS on EX4300 Series, via the pfe-chassisd Chassis Manager (CMLC) daemon. The vulnerability allows an attacker to cause a Denial of Service by sending specific valid broadcast packets that trigger a broadcast storm on the me0 interface, requiri...

CVE-2019-0048

CVE-2019-0048 affects Juniper Networks Junos OS on the EX4300 Series. Root cause: with TCAM optimization enabled, an implicit loopback filter rule (high priority) meant for 224.0.0.x incorrectly matches 224.x.x.x, causing multicast firewall behavior to break when a filter is applied on the loopba...
