Scientific Linux Security Update : kexec-tools on SL7.x x86_64 (20150512)
low Nessus Plugin ID 83452
Language:
Synopsis
The remote Scientific Linux host is missing one or more security updates.Description
It was found that the module-setup.sh script provided by kexec-tools created temporary files in an insecure way. A malicious, local user could use this flaw to conduct a symbolic link attack, allowing them to overwrite the contents of arbitrary files. (CVE-2015-0267)This update also fixes the following bug :
- On Atomic Host systems, the kdump tool previously saved kernel crash dumps in the /sysroot/crash file instead of the /var/crash file. The parsing error that caused this problem has been fixed, and the kernel crash dumps are now correctly saved in /var/crash.
In addition, this update adds the following enhancement :
- The makedumpfile command now supports the new sadump format that can represent more than 16 TB of physical memory space. This allows users of makedumpfile to read dump files over 16 TB, generated by sadump on certain upcoming server models.
Solution
Update the affected kexec-tools, kexec-tools-debuginfo and / or kexec-tools-eppic packages.See Also
