The recently disclosed critical security flaw impacting Apache ActiveMQ is being actively exploited by threat actors to distribute a new Go-based botnet called GoTitan as well as a .NET program known as PrCtrl Rat that's capable of remotely commandeering the infected hosts. The attacks involve the exploitation of a remote code execution bug (CVE-2023-46604, CVSS score: 10.0) that has been

### Summary Calling `load_pem_pkcs7_certificates` or `load_der_pkcs7_certificates` could lead to a NULL-pointer dereference and segfault. ### PoC Here is a Python code that triggers the issue: ```python from cryptography.hazmat.primitives.serialization.pkcs7 import load_der_pkcs7_certificates, load_pem_pkcs7_certificates pem_p7 = b""" -----BEGIN PKCS7----- MAsGCSqGSIb3DQEHAg== -----END PKCS7----- """ der_p7 = b"\x30\x0B\x06\x09\x2A\x86\x48\x86\xF7\x0D\x01\x07\x02" load_pem_pkcs7_certificates(pem_p7) load_der_pkcs7_certificates(der_p7) ``` ### Impact Exploitation of this vulnerability poses a serious risk of Denial of Service (DoS) for any application attempting to deserialize a PKCS7 blob/certificate. The consequences extend to potential disruptions in system availability and stability.

An authenticated malicious user could initiate multiple concurrent requests, each requesting multiple dashboard exports, leading to a possible denial of service. This issue affects Apache Superset: before 3.0.0

Debian Linux Security Advisory 5568-1 - It was discovered that incorrect memory management in Fast DDS, a C++ implementation of the DDS (Data Distribution Service) might result in denial of service.

Ubuntu Security Notice 6513-2 - USN-6513-1 fixed vulnerabilities in Python. This update provides the corresponding updates for Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, and Ubuntu 23.04. It was discovered that Python incorrectly handled certain plist files. If a user or an automated system were tricked into processing a specially crafted plist file, an attacker could possibly use this issue to consume resources, resulting in a denial of service.

Ubuntu Security Notice 6402-2 - USN-6402-1 fixed vulnerabilities in LibTomMath. This update provides the corresponding updates for Ubuntu 23.10. It was discovered that LibTomMath incorrectly handled certain inputs. An attacker could possibly use this issue to execute arbitrary code and cause a denial of service.

Ubuntu Security Notice 6502-2 - Ivan D Barrera, Christopher Bednarz, Mustafa Ismail, and Shiraz Saleem discovered that the InfiniBand RDMA driver in the Linux kernel did not properly check for zero-length STAG or MR registration. A remote attacker could possibly use this to execute arbitrary code. Yu Hao discovered that the UBI driver in the Linux kernel did not properly check for MTD with zero erasesize during device attachment. A local privileged attacker could use this to cause a denial of service.
