CVE-2018-10908
By uploading a specially crafted image, an attacker could cause the qemu-img process to consume unbounded amounts of memory of CPU time, causing a denial of service condition that could potentially impact other users of the host.
Does this matter?
Lower severity and a low EPSS score (1.19%). Track it; it rarely justifies an emergency change on its own.
Description
It was found that vdsm before version 4.20.37 invokes qemu-img on untrusted inputs without limiting resources. By uploading a specially crafted image, an attacker could cause the qemu-img process to consume unbounded amounts of memory of CPU time, causing a denial of service condition that could potentially impact other users of the host.
