In the Linux kernel, the following vulnerability has been resolved: net: sched: actconnmark: initialize struct tcife to prevent kernel leaks. In tcfconnmarkdump, the variable ‘opt’ was partially initialized using a specified initializer. As a result, the padding bytes remained uninitialized. The...

Astra Linux – Vulnerability in Golang-1.19

Parsing multipart forms can consume large amounts of CPU and memory when processing form inputs containing a very large number of parts. This occurs due to several reasons: 1. The mime/multipart.Reader.ReadForm method limits the total memory that a parsed multipart form can consume. ReadForm may...
