CWE-377  (opens in a new tab)

How to fix?

There is no fixed version for RHEL:7 qemu-img.

NVD Description

Note: Versions mentioned in the description apply only to the upstream qemu-img package and not the qemu-img package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

The slirp_smb function in net/slirp.c in QEMU 2.3.0 and earlier creates temporary files with predictable names, which allows local users to cause a denial of service (instantiation failure) by creating /tmp/qemu-smb.- files before the program.
