CVE-2015-5277

Publication date 17 December 2015

Ubuntu priority

Medium

Why this priority?

The get_contents function in nss_files/files-XXX.c in the Name Service Switch (NSS) in GNU C Library (aka glibc or libc6) before 2.20 might allow local users to cause a denial of service (heap corruption) or gain privileges via a long line in the NSS files database.

From the Ubuntu Security Team

Sumit Bose and Lukáš Slebodník discovered that the Name Service Switch (NSS) implementation in the GNU C Library did not handle long lines in the files databases correctly. A local attacker could use this to cause a denial of service (application crash) or possibly execute arbitrary code.
