USN-3536-1: GNU C Library vulnerability
17 January 2018
The GNU C library could be made to run programs as an administrator.
Releases
Packages
- 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
After a standard system update you need to reboot your computer to make
all the necessary changes.
