node-jose is a JavaScript implementation of the JSON Object Signing and Encryption (JOSE) for web browsers and node.js-based servers. Prior to version 2.2.0, when using the non-default "fallback" crypto back-end, ECC operations in `node-jose` can trigger a Denial-of-Service (DoS) condition, due to a possible infinite loop in an internal calculation. For some ECC operations, this condition is triggered randomly; for others, it can be triggered by malicious input. The issue has been patched in version 2.2.0. Since this issue is only present in the "fallback" crypto implementation, it can be avoided by ensuring that either WebCrypto or the Node `crypto` module is available in the JS environment where `node-jose` is being run.
An improper restriction of xml external entity reference in Fortinet FortiNAC version 9.4.0 through 9.4.1, FortiNAC version 9.2.0 through 9.2.7, FortiNAC version 9.1.0 through 9.1.8, FortiNAC version 8.8.0 through 8.8.11, FortiNAC version 8.7.0 through 8.7.6, FortiNAC version 8.6.0 through 8.6.5, FortiNAC version 8.5.0 through 8.5.4, FortiNAC version 8.3.7 allows attacker to read arbitrary files or trigger a denial of service via specifically crafted XML documents.
HashiCorp go-getter up to 1.6.2 and 2.1.1 is vulnerable to decompression bombs. Fixed in 1.7.0 and 2.2.0.
### Description When using the non-default "fallback" crypto back-end, ECC operations in `node-jose` can trigger a Denial-of-Service (DoS) condition, due to a possible infinite loop in an internal calculation. For some ECC operations, this condition is triggered randomly; for others, it can be triggered by malicious input. #### Technical summary The JOSE logic implemented by `node-jose` usually relies on an external cryptographic library for the underlying cryptographic primitives that JOSE operations require. When WebCrypto or the Node `crypto` module are available, they are used. When neither of these libraries is available, `node-jose` includes its own "fallback" implementations of some algorithms based on `node-forge`, in particular implementations of ECDH and ECDSA. A various points, these algorithm implementations need to compute to the X coordinate of an elliptic curve point. This is done by calling the `getX()` method of the object representing the point, which is an a...
Undici is an HTTP/1.1 client for Node.js. Prior to version 5.19.1, the `Headers.set()` and `Headers.append()` methods are vulnerable to Regular Expression Denial of Service (ReDoS) attacks when untrusted values are passed into the functions. This is due to the inefficient regular expression used to normalize the values in the `headerValueNormalize()` utility function. This vulnerability was patched in v5.19.1. No known workarounds are available.
APOC (Awesome Procedures on Cypher) is an add-on library for Neo4j. An XML External Entity (XXE) vulnerability found in the apoc.import.graphml procedure of APOC core plugin prior to version 5.5.0 in Neo4j graph database. XML External Entity (XXE) injection occurs when the XML parser allows external entities to be resolved. The XML parser used by the apoc.import.graphml procedure was not configured in a secure way and therefore allowed this. External entities can be used to read local files, send HTTP requests, and perform denial-of-service attacks on the application. Abusing the XXE vulnerability enabled assessors to read local files remotely. Although with the level of privileges assessors had this was limited to one-line files. With the ability to write to the database, any file could have been read. Additionally, assessors noted, with local testing, the server could be crashed by passing in improperly formatted XML. The minimum version containing a patch for this vulnerability is 5...

Ubuntu Security Notice 5879-1 - Kyle Zeng discovered that the sysctl implementation in the Linux kernel contained a stack-based buffer overflow. A local attacker could use this to cause a denial of service or execute arbitrary code. Tamás Koczka discovered that the Bluetooth L2CAP handshake implementation in the Linux kernel contained multiple use-after-free vulnerabilities. A physically proximate attacker could use this to cause a denial of service or possibly execute arbitrary code.
Ubuntu Security Notice 5878-1 - It was discovered that the Bluetooth HCI implementation in the Linux kernel did not properly deallocate memory in some situations. An attacker could possibly use this cause a denial of service. It was discovered that the Broadcom FullMAC USB WiFi driver in the Linux kernel did not properly perform bounds checking in some situations. A physically proximate attacker could use this to craft a malicious USB device that when inserted, could cause a denial of service or possibly execute arbitrary code.
