Improper Restriction of Operations within the Bounds of a Memory Buffer

A use-after-free flaw was found in fs/userfaultfd.c in the Linux kernel before 4.13.6. The issue is related to the handling of fork failure when dealing with event messages. Failure to fork correctly can lead to a situation where a fork event will be removed from an already freed list of events with userfaultfd_ctx_put().Show less

In Libav through 12.2, there is an invalid memcpy call in the ff_mov_read_stsd_entries function of libavformat/mov.c. Remote attackers could leverage this vulnerability to cause a denial of service (segmentation fault) and program failure with a crafted avi file.Show less

In libMtkOmxVdec.so there is a possible heap buffer overflow. This could lead to a remote elevation of privilege enabling code execution as a privileged process with no additional execution privileges needed. User interaction is needed for exploitation. Product: Android. Versions: Android kernel. Android ID: A-38308024. References: M-ALPS03495789.Show less

In receive_packet of libnetutils/packet.c, there is a possible out-of-bounds write due to a missing bounds check on the DHCP response. This could lead to remote code execution as a privileged process with no additional execution privileges needed. User interaction is not needed for exploitation. Product: Android. Versions: 5.1.1, 6.0, 6.0.1, 7.0, 7.1.1, 7.1.2, 8.0, 8.1. Android ID: A-67474440.Show less

In the ihevcd_parse_slice.c function, slave threads are not joined if there is an error. This could lead to a remote denial of service of a critical system process with no additional execution privileges needed. User interaction is not needed for exploitation. Product: Android. Versions: 6.0, 6.0.1, 7.0, 7.1.1, 7.1.2, 8.0, 8.1. Android ID: A-64784973.Show less

In several functions of libhevc, NEON registers are not preserved. This could lead to remote code execution as a privileged process with no additional execution privileges needed. User interaction is not needed for exploitation. Product: Android. Versions: 5.1.1, 6.0, 6.0.1, 7.0, 7.1.1, 7.1.2, 8.0, 8.1. Android ID: A-68320413.Show less

An issue was discovered in WECON Technology LEVI Studio HMI Editor v1.8.29 and prior. Specially-crafted malicious files may be able to cause stack-based buffer overflow vulnerabilities, which may allow remote code execution.Show less

An unauthenticated network-based attacker able to send a maliciously crafted LLDP packet to the local segment, through a local segment broadcast, may be able to cause a Junos device to enter an improper boundary check condition allowing a memory corruption to occur, leading to a denial of service. Further crafted packets may be able to sustain the denial of service condition. Score: 6.5 MEDIUM (CVSS:3.0/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) Further, if the attacker is authenticated on the target device receiving and processing the malicious LLDP packet, while receiving the crafted packets, the attacker may be able to perform command or arbitrary code injection over the target device thereby elevating their permissions and privileges, and taking control of the device. Score: 7.8 HIGH (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) An unauthenticated network-based attacker able to send a maliciously crafted LLDP packet to one or more local segments, via LLDP proxy / tunneling agents or other LLDP through Layer 3 deployments, through one or more local segment broadcasts, may be able to cause multiple Junos devices to enter an improper boundary check condition allowing a memory corruption to occur, leading to multiple distributed Denials of Services. These Denials of Services attacks may have cascading Denials of Services to adjacent connected devices, impacts network devices, servers, workstations, etc. Further crafted packets may be able to sustain these Denials of Services conditions. Score 6.8 MEDIUM (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:C/C:N/I:N/A:H) Further, if the attacker is authenticated on one or more target devices receiving and processing these malicious LLDP packets, while receiving the crafted packets, the attacker may be able to perform command or arbitrary code injection over multiple target devices thereby elevating their permissions and privileges, and taking control multiple devices. Score: 7.8 HIGH (CVSS:3.0/AV:L/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H) Affected releases are Juniper Networks Junos OS: 12.1X46 versions prior to 12.1X46-D71; 12.3 versions prior to 12.3R12-S7; 12.3X48 versions prior to 12.3X48-D55; 14.1 versions prior to 14.1R8-S5, 14.1R9; 14.1X53 versions prior to 14.1X53-D46, 14.1X53-D50, 14.1X53-D107; 14.2 versions prior to 14.2R7-S9, 14.2R8; 15.1 versions prior to 15.1F2-S17, 15.1F5-S8, 15.1F6-S8, 15.1R5-S7, 15.1R7; 15.1X49 versions prior to 15.1X49-D90; 15.1X53 versions prior to 15.1X53-D65; 16.1 versions prior to 16.1R4-S6, 16.1R5; 16.1X65 versions prior to 16.1X65-D45; 16.2 versions prior to 16.2R2; 17.1 versions prior to 17.1R2.

On SRX Series and MX Series devices with a Service PIC with any ALG enabled, a crafted TCP/IP response packet processed through the device results in memory corruption leading to a flowd daemon crash. Sustained crafted response packets lead to repeated crashes of the flowd daemon which results in an extended Denial of Service condition. Affected releases are Juniper Networks Junos OS: 12.1X46 versions prior to 12.1X46-D60 on SRX series; 12.3X48 versions prior to 12.3X48-D35 on SRX series; 14.1 versions prior to 14.1R9 on MX series; 14.2 versions prior to 14.2R8 on MX series; 15.1X49 versions prior to 15.1X49-D60 on SRX series; 15.1 versions prior to 15.1R5-S8, 15.1F6-S9, 15.1R6-S4, 15.1R7 on MX series; 16.1 versions prior to 16.1R6 on MX series; 16.2 versions prior to 16.2R3 on MX series; 17.1 versions prior to 17.1R2-S4, 17.1R3 on MX series.
