High Nessus Plugin ID 86865

Synopsis

Description

xen was updated to fix eight security issues.

These security issues were fixed :

- CVE-2015-4037: The slirp_smb function in net/slirp.c created temporary files with predictable names, which allowed local users to cause a denial of service (instantiation failure) by creating /tmp/qemu-smb.*-* files before the program (bsc#932267).

- CVE-2015-6815: With e1000 NIC emulation support it was possible to enter an infinite loop (bsc#944697).

- CVE-2015-7969: Leak of per-domain profiling- related vcpu pointer array leading to denial of service (bsc#950705).

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
