By Jon Munshaw.  Welcome to this week’s edition of the Threat Source newsletter.  I’ve been thinking a lot recently about the pros and cons of the way we publicize our threat research. I had a few conversations at Cisco Live with people — who are more generally IT-focused than... [[ This is only the beginning! Please visit the blog for the complete entry ]]

A minor version update (from 7.10 to 7.11) is now available for Red Hat Fuse. The purpose of this text-only errata is to inform you about the security issues fixed in this release.

A memory corruption in Hex Rays Ida Pro v6.6 allows attackers to cause a Denial of Service (DoS) via a crafted file. Related to Data from Faulting Address controls subsequent Write Address starting at msvcrt!memcpy+0x0000000000000056.

1. EXECUTIVE SUMMARY CVSS v3 9.1 ATTENTION: Exploitable remotely/low attack complexity Vendor: Bently Nevada Equipment: 3701/4X series and 60M100 (3701/60) Condition Monitoring System Vulnerabilities: Use of Hard-coded Credentials, Missing Authentication for Critical Function CISA is aware of a public report, known as “OT:ICEFALL” that details vulnerabilities found in multiple operational technology (OT) vendors. CISA is issuing this advisory to provide notice of the reported vulnerabilities and identify baseline mitigations for reducing risks to these and other cybersecurity attacks. 2. RISK EVALUATION Successful exploitation of these vulnerabilities could allow file manipulation, remote code execution, or cause a denial-of-service condition. 3. TECHNICAL DETAILS 3.1 AFFECTED PRODUCTS The following versions of Bently Nevada 3700 machinery monitors are affected: Bently Nevada 3701/40: All versions prior to 4.1 Bently Nevada 3701/44: All versions prior to 4.1 Bently Nevada 3701/46: All ...

It's time to tap the large reservoir of talent with analytical skills to help tackle cybersecurity problems. Train workers in cybersecurity details while using their ability to solve problems.

A malicious server can serve excessive amounts of `Set-Cookie:` headers in a HTTP response to curl and curl < 7.84.0 stores all of them. A sufficiently large amount of (big) cookies make subsequent HTTP requests to this, or other servers to which the cookies match, create requests that become larger than the threshold that curl uses internally to avoid sending crazy large requests (1048576 bytes) and instead returns an error.This denial state might remain for as long as the same cookies are kept, match and haven't expired. Due to cookie matching rules, a server on `foo.example.com` can set cookies that also would match for `bar.example.com`, making it it possible for a "sister server" to effectively cause a denial of service for a sibling site on the same second level domain using this method.

Ubuntu Security Notice 5505-1 - Norbert Slusarek discovered a race condition in the CAN BCM networking protocol of the Linux kernel leading to multiple use-after-free vulnerabilities. A local attacker could use this issue to execute arbitrary code. Likang Luo discovered that a race condition existed in the Bluetooth subsystem of the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.

Cisco on Wednesday rolled out patches for 10 security flaws spanning multiple products, one of which is rated Critical in severity and could be weaponized to conduct absolute path traversal attacks. The issues, tracked as CVE-2022-20812 and CVE-2022-20813, affect Cisco Expressway Series and Cisco TelePresence Video Communication Server (VCS) and "could allow a remote attacker to overwrite

A vulnerability in Cisco Smart Software Manager On-Prem (SSM On-Prem) could allow an authenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to incorrect handling of multiple simultaneous device registrations on Cisco SSM On-Prem. An attacker could exploit this vulnerability by sending multiple device registration requests to Cisco SSM On-Prem. A successful exploit could allow the attacker to cause a DoS condition on an affected device.

OpenVPN Access Server 2.10 and prior versions are susceptible to resending multiple packets in a response to a reset packet sent from the client which the client again does not respond to, resulting in a limited amplification attack.
