In WAGO I/O-Check Service in multiple products an unauthenticated remote attacker can send a specially crafted packet containing OS commands to crash the iocheck process and write memory resulting in loss of integrity and DoS.

The Swiss Army knife-like browser extension is heaven for attackers — and can be hell for enterprise users.

Ubuntu Security Notice 5719-1 - It was discovered that OpenJDK incorrectly handled long client hostnames. An attacker could possibly use this issue to cause the corruption of sensitive information. It was discovered that OpenJDK incorrectly randomized DNS port numbers. A remote attacker could possibly use this issue to perform spoofing attacks. It was discovered that OpenJDK did not limit the number of connections accepted from HTTP clients. An attacker could possibly use this issue to cause a denial of service.

Ubuntu Security Notice 5717-1 - It was discovered that PHP incorrectly handled certain gzip files. An attacker could possibly use this issue to cause a denial of service. It was discovered that PHP incorrectly handled certain cookies. An attacker could possibly use this issue to compromise the data It was discovered that PHP incorrectly handled certain image fonts. An attacker could possibly use this issue to expose sensitive information. This issue only affected Ubuntu 20.04 LTS, Ubuntu 22.10, and Ubuntu 22.04 LTS.

Ubuntu Security Notice 5718-1 - Maddie Stone discovered that pixman incorrectly handled certain memory operations. A remote attacker could use this issue to cause pixman to crash, resulting in a denial of service, or possibly execute arbitrary code.

An issue was discovered in Python before 3.11.1. An unnecessary quadratic algorithm exists in one path when processing some inputs to the IDNA (RFC 3490) decoder, such that a crafted, unreasonably long name being presented to the decoder could lead to a CPU denial of service. Hostnames are often supplied by remote servers that could be controlled by a malicious actor; in such a scenario, they could trigger excessive CPU consumption on the client attempting to make use of an attacker-supplied supposed hostname. For example, the attack payload could be placed in the Location header of an HTTP response with status code 302. A fix is planned in 3.11.1, 3.10.9, 3.9.16, 3.8.16, and 3.7.16.

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 off-by-one Error issue was discovered in Systemd in format_timespan() function of time-util.c. An attacker could supply specific values for time and accuracy that leads to buffer overrun in format_timespan(), leading to a Denial of Service.

In MMU_UnmapPages of the PowerVR kernel driver, there is a possible out of bounds write due to a missing bounds check. This could lead to local escalation of privilege with no additional execution privileges needed.
