========================================================================== Ubuntu Security Notice USN-3536-1 January 17, 2018
eglibc vulnerability ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.04 ESM
Summary:
The GNU C library could be made to run programs as an administrator.
Software Description: - eglibc: GNU C Library
Details:
It was discovered that the GNU C library did not properly handle all of the possible return values from the kernel getcwd(2) syscall. A local attacker could potentially exploit this to execute arbitrary code in setuid programs and gain administrative privileges. (CVE-2018-1000001)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 12.04 ESM: libc6 2.15-0ubuntu10.21
After a standard system update you need to reboot your computer to make all the necessary changes.
