| Description: | The glibc packages provide the standard C libraries (libc), POSIX threadlibraries (libpthread), standard math libraries (libm), and the NameServer Caching Daemon (nscd) used by multiple programs on the system.Without these libraries, the Linux system cannot function correctly.A heap-based buffer overflow was found in glibc's__nss_hostname_digits_dots() function, which is used by the gethostbyname()and gethostbyname2() glibc function calls. A remote attacker able to makean application call either of these functions could use this flaw toexecute arbitrary code with the permissions of the user running theapplication. (CVE-2015-0235)Red Hat would like to thank Qualys for reporting this issue.All glibc users are advised to upgrade to these updated packages, whichcontain a backported patch to correct this issue. |
