<p>An information disclosure vulnerability exists in the way Azure WaLinuxAgent creates swap files on resource disks. An authenticated attacker who successfully exploited this vulnerability could view data in swap that is normally hidden.</p> <p>None of the Azure endorsed <a href="https://docs.microsoft.com/en-us/azure/virtual-machines/linux/endorsed-distros">distros</a> are vulnerable to this issue by default, but this can occur on customer customized or modified images when swapfile is created by the Azure linux agent and python3 is enabled as the default python version.</p> <p>This update addresses this vulnerability by preventing how the swap information is accessed.</p>
