Ubuntu Security Notice USN-3534-1
Posted Jan 17, 2018
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 3534-1 - It was discovered that the GNU C library did not properly handle all of the possible return values from the kernel getcwd syscall. A local attacker could potentially exploit this to execute arbitrary code in setuid programs and gain administrative privileges. A memory leak was discovered in the _dl_init_paths function in the GNU C library dynamic loader. A local attacker could potentially exploit this with a specially crafted value in the LD_HWCAP_MASK environment variable, in combination with CVE-2017-1000409 and another vulnerability on a system with hardlink protections disabled, in order to gain administrative privileges. Various other issues were also addressed.
