In the Linux kernel, the following vulnerability has been resolved: soc: qcom: qmiencdec: Restrict string length in decode The QMI TLV value for strings in many qmi element information structures accounts for null-terminated strings with a length of MAXLEN + 1. If a string actually has a length o...

Astra Linux – Vulnerability in Apache2

Apache HTTP Server versions 2.4.41 to 2.4.46 with modproxyhttp can become unstable when processing specially crafted requests that use both Content-Length and Transfer-Encoding headers. This can lead to a denial of service...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: CDC-NCM: Avoid overflows in sanity checks. A malfunctioning device may produce an extreme offset like 0xFFF0, along with a fragment of reasonable length. In the currently formulated sanity check, this will cause an integer...
