In the Linux kernel, the following vulnerability has been resolved: netfilter: nfsetpipapo: Fix for the initial map filling issue. The initial buffer must be initialized to “all-ones”, but this must be limited to the size of the first field, not the total field size. After each round of the map...

Astra Linux – Vulnerability in Zabbix

When a URL is added to the map element, it is recorded in the database with a sequential ID. When adding a new URL, the system retrieves the previous value of the sysmapelementurlid and increments it by one. However, an issue arises when a user manually changes the sysmapelementurlid value by...
