CVE-2023-34325

CVE-2023-34325 concerns Xen’s copy of libfsimage (derived from grub) used by pygrub. A stack buffer overflow can be triggered by guest-controlled input when pygrub runs with superuser privileges in a privileged domain. Xen notes patches to run pygrub in deprivileged mode to avoid exploitation. CV...

CVE-2023-4949

CVE-2023-4949 involves a memory corruption vulnerability in grub-legacy’s XFS filesystem handling when a modified XFS partition is presented to grub by an attacker with local system access. Affected component: grub-legacy’s XFS file system implementation (via libfsimage/pygrub code paths). Impact...

Multiple vulnerabilities in libfsimage disk handling

ISSUE DESCRIPTION libfsimage contains parsing code for several filesystems, most of them based on grub-legacy code. libfsimage is used by pygrub to inspect guest disks. Pygrub runs as the same user as the toolstack root in a priviledged domain. At least one issue has been reported to the Xen...
