An HTTP Request Forgery issue was discovered in Varnish Cache 5.x and 6.x before 6.0.11, 7.x before 7.1.2, and 7.2.x before 7.2.1. An attacker may introduce characters through HTTP/2 pseudo-headers that are invalid in the context of an HTTP/1 request line, causing the Varnish server to produce invalid HTTP/1 requests to the backend. This could, in turn, be used to exploit vulnerabilities in a server behind the Varnish server. Note: the 6.0.x LTS series (before 6.0.11) is affected.

Microsoft's latest round of monthly security updates has been released with fixes for 68 vulnerabilities spanning its software portfolio, including patches for six actively exploited zero-days. 12 of the issues are rated Critical, two are rated High, and 55 are rated Important in severity. This also includes the weaknesses that were closed out by OpenSSL the previous week. Also separately

An information leakage vulnerability in the Bluetooth Low Energy advertisement scan response in Bluetooth Core Specifications 4.0 through 5.2, and extended scan response in Bluetooth Core Specifications 5.0 through 5.2, may be used to identify devices using Resolvable Private Addressing (RPA) by their response or non-response to specific scan requests from remote addresses. RPAs that have been associated with a specific remote device may also be used to identify a peer in the same manner by using its reaction to an active scan request. This has also been called an allowlist-based side channel.

Debian Linux Security Advisory 5272-1 - Multiple vulnerabilities have been discovered in the Xen hypervisor, which could result in privilege escalation, denial of service or information leaks.

Debian Linux Security Advisory 5271-1 - Several vulnerabilities were discovered in libxml2, a library providing support to read, modify and write XML and HTML files.

In s::can moni::tools in versions below 4.2 an unauthenticated attacker could get any file from the device by path traversal in the camera-file module.

Debian Linux Security Advisory 5270-1 - Yuchen Zeng and Eduardo Vela discovered a buffer overflow in NTFS-3G, a read-write NTFS driver for FUSE, due to incorrect validation of some of the NTFS metadata. A local user can take advantage of this flaw for local root privilege escalation.

Zettlr version 2.3.0 allows an external attacker to remotely obtain arbitrary local files on any client that attempts to view a malicious markdown file through Zettlr. This is possible because the application does not have a CSP policy (or at least not strict enough) and/or does not properly validate the contents of markdown files before rendering them.

Debian Linux Security Advisory 5269-1 - Nicky Mouha discovered a buffer overflow in the sha3 module of PyPy, a fast, compliant alternative implementation of the Python language.

Debian Linux Security Advisory 5268-1 - Several vulnerabilities have been discovered in the FFmpeg multimedia framework, which could result in denial of service or potentially the execution of arbitrary code if malformed files/streams are processed.
