Mishandling of uninitialised FIFO-based event channel control blocks XSA-107, CVE-2014-6268 Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible...

Mishandling of uninitialised FIFO-based event channel control blocks

ISSUE DESCRIPTION When using the FIFO-based event channels, there are no checks for the existence of a control block when binding an event or moving it to a different VCPU. This is because events may be bound when the ABI is in 2-level mode e.g., by the toolstack before the domain is started. The...

CVE-2012-1090

CVE-2012-1090 affects the Linux kernel: the cifs_lookup function in fs/cifs/dir.c can trigger a local denial of service (OOPS) when a local user accesses a specially crafted file (e.g., a FIFO). The issue exists in kernel versions prior to 3.2.10. Exploitation requires local access. The documente...
