An updated libnih package that adds one enhancement is now available for Red Hat Enterprise Linux 6.
The libnih package includes a small library for C application development. The library is similar to other C libraries, such as glib.
Previously, the libnih package was compiled without the read-only relocations (RELRO) flag. Programs built against the libnih library could be vulnerable to various attacks based on overwriting the ELF section of a program. To enhance the security, the libnih package is now provided with partial RELRO support.
All users of libnih are advised to upgrade to this updated package, which adds this enhancement.
