RHBA-2012:0566 - glibc bug fix update

Synopsis

glibc bug fix update

Type/Severity

Bug Fix Advisory

Topic

Updated glibc packages that fix two bugs are now available for Red Hat Enterprise Linux 6.

Description

The glibc packages provide the standard C and standard math libraries used by multiple programs on the system. Without these libraries, the Linux system cannot function correctly.

This update fixes the following bugs:

  • Previously, glibc looked for an error condition in the wrong location and failed to process a second response buffer in the gaih_getanswer() function. As a consequence, the getaddrinfo() function could not properly return all addresses. This update fixes an incorrect error test condition in gaih_getanswer() so that glibc now correctly parses the second response buffer. The getaddrinfo() function now correctly returns all addresses. (BZ#802855)

  • Previously, if the nscd daemon received a CNAME (Canonical Name) record as a response to a DNS (Domain Name System) query, the cached DNS entry adopted the TTL (Time to Live) value of the underlying "A" or "AAAA" response. This caused the nscd daemon to wait for an unexpectedly long time before reloading the DNS entry. With this update, nscd uses the shortest TTL from the response as the TTL value for the entire record. DNS entries are reloaded as expected in this scenario. (BZ#813859)

All users of glibc are advised to upgrade to these updated packages, which fix these bugs.

Solution

Before applying this update, make sure all previously-released errata relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at This content is not included.https://access.redhat.com/kb/docs/DOC-11259
