CVE-2019-0053 – Junos OS: Insufficient validation of environment variables in telnet client may lead to stack-based buffer overflow

https://notcve.org/view.php?id=CVE-2019-0053

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 the telnet client to remote telnet servers. This issue only affects the telnet client — accessible from the CLI or shell — in Junos OS. Inbound telnet services are not affected by this issue. This issue affects: Juniper Networks Junos OS: 12.3 versions prior to 12.3R12-S13; 12.3X48 versions prior to 12.3X48-D80; 14.1X53 versions prior to 14.1X53-D130, 14.1X53-D49; 15.1 versions prior to 15.1F6-S12, 15.1R7-S4; 15.1X49 versions prior to 15.1X49-D170; 15.1X53 versions prior to 15.1X53-D237, 15.1X53-D496, 15.1X53-D591, 15.1X53-D69; 16.1 versions prior to 16.1R3-S11, 16.1R7-S4; 16.2 versions prior to 16.2R2-S9; 17.1 versions prior to 17.1R3; 17.2 versions prior to 17.2R1-S8, 17.2R2-S7, 17.2R3-S1; 17.3 versions prior to 17.3R3-S4; 17.4 versions prior to 17.4R1-S6, 17.4R2-S3, 17.4R3; 18.1 versions prior to 18.1R2-S4, 18.1R3-S3; 18.2 versions prior to 18.2R1-S5, 18.2R2-S2, 18.2R3; 18.2X75 versions prior to 18.2X75-D40; 18.3 versions prior to 18.3R1-S3, 18.3R2; 18.4 versions prior to 18.4R1-S2, 18.4R2. • https://github.com/dreamsmasher/inetutils-CVE-2019-0053-Patched-PKGBUILD http://packetstormsecurity.com/files/153746/FreeBSD-Security-Advisory-FreeBSD-SA-19-12.telnet.html https://kb.juniper.net/JSA10947 https://lists.debian.org/debian-lts-announce/2022/11/msg00033.html https://lists.debian.org/debian-lts-announce/2023/10/msg00013.html https://seclists.org/bugtraq/2019/Jul/45 https://security.FreeBSD.org/advisories/FreeBSD-SA-19:12.telnet.asc https://www.exploit-db.com/exploits/45982 • CWE-121: Stack-based Buffer Overflow CWE-787: Out-of-bounds Write •

CVE-2019-0044 – Junos OS: SRX5000 series: Kernel crash (vmcore) upon receipt of a specific packet on fxp0 interface

https://notcve.org/view.php?id=CVE-2019-0044

Receipt of a specific packet on the out-of-band management interface fxp0 may cause the system to crash and restart (vmcore). By continuously sending a specially crafted packet to the fxp0 interface, an attacker can repetitively crash the rpd process causing prolonged Denial of Service (DoS). Affected releases are Juniper Networks SRX5000 Series: 12.1X46 versions prior to 12.1X46-D82; 12.3X48 versions prior to 12.3X48-D80; 15.1X49 versions prior to 15.1X49-D160. La recepción de un paquete específico en la interfaz de administración fuera de banda fxp0 puede hacer que el sistema se bloquee y se reinicie (vmcore). Mediante el envío continuo de un paquete especialmente creado a la interfaz fxp0, un atacante puede bloquear repetitivamente el proceso rpd y provocar una denegación de servicio (DoS) prolongada. • http://www.securityfocus.com/bid/107872 https://kb.juniper.net/JSA10936 • CWE-404: Improper Resource Shutdown or Release •

https://notcve.org/view.php?id=CVE-2019-0043

In MPLS environments, receipt of a specific SNMP packet may cause the routing protocol daemon (RPD) process to crash and restart. By continuously sending a specially crafted SNMP packet, an attacker can repetitively crash the RPD process causing prolonged denial of service. No other Juniper Networks products or platforms are affected by this issue. Affected releases are Juniper Networks Junos OS : 12.1X46 versions prior to 12.1X46-D77 on SRX Series; 12.3 versions prior to 12.3R12-S10; 12.3X48 versions prior to 12.3X48-D75 on SRX Series; 14.1X53 versions prior to 14.1X53-D48 on EX/QFX series; 15.1 versions prior to 15.1R4-S9, 15.1R7-S2; 15.1F6 versions prior to 15.1F6-S11; 15.1X49 versions prior to 15.1X49-D141, 15.1X49-D144, 15.1X49-D150 on SRX Series; 15.1X53 versions prior to 15.1X53-D234 on QFX5200/QFX5110 Series; 15.1X53 versions prior to 15.1X53-D68 on QFX10K Series; 15.1X53 versions prior to 15.1X53-D471, 15.1X53-D490 on NFX Series; 15.1X53 versions prior to 15.1X53-D590 on EX2300/EX3400 Series; 15.1X54 on ACX Series; 16.1 versions prior to 16.1R3-S10, 16.1R4-S11, 16.1R6-S5, 16.1R7; 16.1X65 versions prior to 16.1X65-D48; 16.2 versions prior to 16.2R2-S6; 17.1 versions prior to 17.1R2-S8, 17.1R3; 17.2 versions prior to 17.2R1-S7, 17.2R3; 17.2X75 versions prior to 17.2X75-D92, 17.2X75-D102, 17.2X75-D110; 17.3 versions prior to 17.3R3; 17.4 versions prior to 17.4R1-S4, 17.4R2; 18.1 versions prior to 18.1R1-S1, 18.1R2-S1, 18.1R3; 18.2X75 versions prior to 18.2X75-D10.

CVE-2019-0036 – Junos OS: Firewall filter terms named "internal-1" and "internal-2" being ignored

https://notcve.org/view.php?id=CVE-2019-0036

When configuring a stateless firewall filter in Junos OS, terms named using the format "internal-n" (e.g. "internal-1", "internal-2", etc.) are silently ignored. No warning is issued during configuration, and the config is committed without error, but the filter criteria will match all packets leading to unexpected results. Affected releases are Juniper Networks Junos OS: All versions prior to and including 12.3; 14.1X53 versions prior to 14.1X53-D130, 14.1X53-D49; 15.1 versions prior to 15.1F6-S12, 15.1R7-S4; 15.1X49 versions prior to 15.1X49-D161, 15.1X49-D170; 15.1X53 versions prior to 15.1X53-D236, 15.1X53-D496, 15.1X53-D69; 16.1 versions prior to 16.1R7-S4, 16.1R7-S5; 16.2 versions prior to 16.2R2-S9; 17.1 versions prior to 17.1R3; 17.2 versions prior to 17.2R1-S8, 17.2R3-S1; 17.3 versions prior to 17.3R3-S4; 17.4 versions prior to 17.4R1-S7, 17.4R2-S3; 18.1 versions prior to 18.1R2-S4, 18.1R3-S4; 18.2 versions prior to 18.2R1-S5, 18.2R2-S1; 18.2X75 versions prior to 18.2X75-D40; 18.3 versions prior to 18.3R1-S3; 18.4 versions prior to 18.4R1-S1, 18.4R1-S2. Cuando se configura un filtro de cortafuegos sin estado en Junos OS, los términos nombrados con el formato "internal-n" (por ejemplo, "internal-1", "internal-2", etc.) se ignoran en silencio. • https://kb.juniper.net/JSA10925 • CWE-284: Improper Access Control CWE-754: Improper Check for Unusual or Exceptional Conditions •
