Synopsis
The remote Oracle Linux host is missing one or more security updates.Description
The remote Oracle Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2020-5936 advisory.- arch/x86/kernel/entry_32.S in the Linux kernel through 3.15.1 on 32-bit x86 platforms, when syscall auditing is enabled and the sep CPU feature flag is set, allows local users to cause a denial of service (OOPS and system crash) via an invalid syscall number, as demonstrated by number 1000. (CVE-2014-4508)
- The omninet_open function in drivers/usb/serial/omninet.c in the Linux kernel before 4.10.4 allows local users to cause a denial of service (tty exhaustion) by leveraging reference count mishandling.
(CVE-2017-8925)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
