The package ua-parser-js before 0.7.23 are vulnerable to Regular Expression Denial of Service (ReDoS) in multiple regexes (see linked commit for more info).

The PROFINET (PNIO) stack, when integrated with the Interniche IP stack, improperly handles internal resources for TCP segments where the minimum TCP-Header length is less than defined. This could allow an attacker to create a denial of service condition for TCP services on affected devices by sending specially crafted TCP segments.

In Expat (aka libexpat) before 2.4.5, there is an integer overflow in copyString.

A vulnerability has been identified in Opcenter Execution Discrete (All versions < V3.2), Opcenter Execution Foundation (All versions < V3.2), Opcenter Execution Process (All versions < V3.2), Opcenter Intelligence (All versions < V3.3), Opcenter Quality (All versions < V11.3), Opcenter RD&L (V8.0), SIMATIC IT LMS (All versions < V2.6), SIMATIC IT Production Suite (All versions < V8.0), SIMATIC Notifier Server for Windows (All versions), SIMATIC PCS neo (All versions < V3.0 SP1), SIMATIC STEP 7 (TIA Portal) V15 (All versions < V15.1 Update 5), SIMATIC STEP 7 (TIA Portal) V16 (All versions < V16 Update 2), SIMOCODE ES V15.1 (All versions < V15.1 Update 4), SIMOCODE ES V16 (All versions < V16 Update 1), Soft Starter ES V15.1 (All versions < V15.1 Update 3), Soft Starter ES V16 (All versions < V16 Update 1). Sending a specially crafted packet to the affected service could cause a partial remote denial-of-service, that would cause the service to restart itself.

A vulnerability has been identified in SIMATIC S7-200 SMART CPU family (All versions >= V2.2 < V2.5.1). Affected devices do not properly handle large numbers of new incomming connections and could crash under certain circumstances. An attacker may leverage this to cause a Denial-of-Service situation.

The Diffie-Hellman Key Agreement Protocol allows remote attackers (from the client side) to send arbitrary numbers that are actually not public keys, and trigger expensive server-side DHE modular-exponentiation calculations, aka a D(HE)at or D(HE)ater attack. The client needs very little CPU resources and network bandwidth. The attack may be more disruptive in cases where a client can require a server to select its largest supported key size. The basic attack scenario is that the client must claim that it can only communicate with DHE, and the server must be configured to allow DHE.

Siemens 3568i WAP mobile phones allows remote attackers to cause a denial of service (crash) via an SMS message containing unusual characters.

An issue was discovered in Mbed TLS before 2.25.0 (and before 2.16.9 LTS and before 2.7.18 LTS). The calculations performed by mbedtls_mpi_exp_mod are not limited; thus, supplying overly large parameters could lead to denial of service when generating Diffie-Hellman key pairs.

An issue was discovered in HCC Nichestack 3.0. The code that parses TCP packets relies on an unchecked value of the IP payload size (extracted from the IP header) to compute the length of the TCP payload within the TCP checksum computation function. When the IP payload size is set to be smaller than the size of the IP header, the TCP checksum computation function may read out of bounds (a low-impact write-out-of-bounds is also possible).

An issue was discovered in HCC Nichestack 3.0. The code that parses ICMP packets relies on an unchecked value of the IP payload size (extracted from the IP header) to compute the ICMP checksum. When the IP payload size is set to be smaller than the size of the IP header, the ICMP checksum computation function may read out of bounds, causing a Denial-of-Service.

Lodash versions prior to 4.17.21 are vulnerable to Regular Expression Denial of Service (ReDoS) via the toNumber, trim and trimEnd functions.

Affected devices contain a vulnerability that allows an unauthenticated attacker to trigger a denial of service condition. The vulnerability can be triggered if a large amount of DCP reset packets are sent to the device.

A vulnerability has been identified in SIMATIC MV400 family (All Versions < V7.0.6). The underlying TCP stack of the affected products does not correctly validate the sequence number for incoming TCP RST packages. An attacker could exploit this to terminate arbitrary TCP sessions.

UltraVNC revision 1211 has a stack buffer overflow vulnerability in VNC server code inside file transfer request handler, which can result in Denial of Service (DoS). This attack appears to be exploitable via network connectivity. This vulnerability has been fixed in revision 1212.

UltraVNC revision 1206 has stack-based Buffer overflow vulnerability in VNC client code inside FileTransfer module, which leads to a denial of service (DoS) condition. This attack appear to be exploitable via network connectivity. This vulnerability has been fixed in revision 1207.

The webserver of the affected devices contains a vulnerability that may lead to a denial of service condition. An attacker may cause a denial of service situation which leads to a restart of the webserver of the affected device. The security vulnerability could be exploited by an attacker with network access to the affected systems. Successful exploitation requires no system privileges and no user interaction. An attacker could use the vulnerability to compromise availability of the device.

A vulnerability has been identified in SINAMICS PERFECT HARMONY GH180 with NXG I control, MLFBs: 6SR2...-, 6SR3...-, 6SR4...- (All Versions with option G21, G22, G23, G26, G28, G31, G32, G38, G43 or G46), SINAMICS PERFECT HARMONY GH180 with NXG II control, MLFBs: 6SR2...-, 6SR3...-, 6SR4...- (All Versions with option G21, G22, G23, G26, G28, G31, G32, G38, G43 or G46). An improperly configured Parameter Read/Write execution via Field bus network may cause the controller to restart. The vulnerability could be exploited by an attacker with network access to the device. Successful exploitation requires no privileges and no user interaction. An attacker could use the vulnerability to compromise the availability of the affected system. At the time of advisory publication no public exploitation of this security vulnerability was known.
