Improper Check for Unusual or Exceptional Conditions

An Improper Check for Unusual or Exceptional Conditions (CWE-754) vulnerability exists in Modicon Quantum 140 NOE771x1 version 6.9 and earlier, which could cause denial of service when the module receives an IP fragmented packet with a length greater than 65535 bytes. The module then requires a power cycle to recover.Show less

An exploitable denial of service vulnerability exists in the object lookup functionality of Yara 3.8.1. A specially crafted binary file can cause a negative value to be read to satisfy an assert, resulting in Denial of Service. An attacker can create a malicious binary to trigger this vulnerability.Show less

DaveGamble/cJSON cJSON 1.7.8 is affected by: Improper Check for Unusual or Exceptional Conditions. The impact is: Null dereference, so attack can cause denial of service. The component is: cJSON_GetObjectItemCaseSensitive() function. The attack vector is: crafted json file. The fixed version is: 1.7.9 and later.Show less

An unhandled exception vulnerability exists during Google Sign-In with Google API C++ Client before 2019-04-10. It potentially causes an outage of third-party services that were not designed to recover from exceptions. On the client, ID token handling can cause an unhandled exception because of misinterpretation of an integer as a string, resulting in denial-of-service and then other users can no longer login/sign-in to the affected third-party service. Once this third-party service uses Google Sign-In with google-api-cpp-client, a malicious user can trigger this client/auth/oauth2_authorization.cc vulnerability by requesting the client to receive the ID token from a Google authentication server.Show less

A CWE-754 Improper Check for Unusual or Exceptional Conditions vulnerability exists in Triconex TriStation Emulator V1.2.0, which could cause the emulator to crash when sending a specially crafted packet. The emulator is used infrequently for application logic testing. It is susceptible to an attack only while running in off-line mode. This vulnerability does not exist in Triconex hardware products and therefore has no effect on the operating safety functions in a plant.Show less

A CWE-754: Improper Check for Unusual or Exceptional Conditions vulnerability exists which could cause a possible Denial of Service when specific Modbus frames are sent to the controller in the products: Modicon M340 - firmware versions prior to V3.01, Modicon M580 - firmware versions prior to V2.80, All firmware versions of Modicon Quantum and Modicon Premium.Show less

A vulnerability in the Border Gateway Patrol (BGP) Multiprotocol Label Switching (MPLS)-based Ethernet VPN (EVPN) implementation of Cisco IOS XR Software could allow an unauthenticated, adjacent attacker to trigger a denial of service (DoS) condition on an affected device. The vulnerability is due to a logic error that occurs when the affected software processes specific EVPN routing information. An attacker could exploit this vulnerability by injecting malicious traffic patterns into the targeted EVPN network. A successful exploit could result in a crash of the l2vpn_mgr process on Provider Edge (PE) device members of the same EVPN instance (EVI). On each of the affected devices, a crash could lead to system instability and the inability to process or forward traffic through the device, resulting in a DoS condition that would require manual intervention to restore normal operating conditions.Show less

An exploitable denial-of-service vulnerability exists in the XML_GetScreen Wi-Fi command of the NT9665X Chipset firmware, running on the Anker Roav A1 Dashcam, version RoavA1SWV1.9. A specially crafted set of packets can cause an invalid memory dereference, resulting in a device reboot.Show less

The tiff_document_render() and tiff_document_get_thumbnail() functions in the TIFF document backend in GNOME Evince through 3.32.0 did not handle errors from TIFFReadRGBAImageOriented(), leading to uninitialized memory use when processing certain TIFF image files.Show less

NVIDIA Jetson TX2 contains a vulnerability in the kernel driver (on all versions prior to R28.3) where the ARM System Memory Management Unit (SMMU) improperly checks for a fault condition, causing transactions to be discarded, which may lead to denial of service.Show less

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.Show less

Zcash, before the Sapling network upgrade (2018-10-28), had a counterfeiting vulnerability. A key-generation process, during evaluation of polynomials related to a to-be-proven statement, produced certain bypass elements. Availability of these elements allowed a cheating prover to bypass a consistency check, and consequently transform the proof of one statement into an ostensibly valid proof of a different statement, thereby breaking the soundness of the proof system. This misled the original Sprout zk-SNARK verifier into accepting the correctness of a transaction.Show less
