When a binary is built with the "RELRO" flag, the ELF sections are reordered to include internal data sections before program's data sections, and the Global Offset Table (GOT) address section of the resulting ELF file is mapped read-only. This ensures that any attempt to overwrite the GOT entry and gain control over the execution flow of a program fails with an error. Because of this, the xinetd daemon is now compiled with full RELRO by using the "-Wl,-z,relro,-z,now" gcc option. (BZ#676013)

When a log file of a xinetd-controlled service exceeded the size limit specified in its configuration file, xinetd terminated unexpectedly with a segmentation fault. With this update, a patch has been applied to address this issue, and the xinetd daemon no longer crashes. (BZ#678493)
