Since glibc-2.34 makes a potentially risky change of moving all functions into the main library, and another inconvenient (for us) change of renaming the library files, we'll stick with glibc-2.33 for Slackware 15.0 and test the newer glibc in the next release cycle. But we'll backport the security fixes from glibc-2.34 with this update: The nameserver caching daemon (nscd), when processing a request for netgroup lookup, may crash due to a double-free, potentially resulting in degraded service or Denial of Service on the local system. Reported by Chris Schanzle. The mq_notify function has a potential use-after-free issue when using a notification type of SIGEV_THREAD and a thread attribute with a non-default affinity mask. The wordexp function may overflow the positional parameter number when processing the expansion resulting in a crash. Reported by Philippe Antoine.

+ 28011)
+
+Use strtoul instead of atoi so that overflow can be detected.
