Package : udisks2
Version : 2.8.1-4+deb10u1
CVE ID : CVE-2021-3802
Debian Bug :

Stefan Walter found that udisks2, a service to access and manipulate storage
devices, could cause denial of service via system crash if a corrupted or
specially crafted ext2/3/4 device or image was mounted, which could happen
automatically on certain environments.

For Debian 10 buster, this problem has been fixed in version
2.8.1-4+deb10u1.

We recommend that you upgrade your udisks2 packages.
