RHBA-2011:0784 - xinetd bug fix update
Synopsis
xinetd bug fix update
Type/Severity
Bug Fix Advisory (none)
Topic
An updated xinetd package that fixes two bugs is now available for Red Hat Enterprise Linux 6.
Description
The xinetd daemon is a secure replacement for inetd, the Internet services daemon. It provides access control for all services based on the address of the remote host and/or on time of access, and can prevent denial of service attacks.
This update fixes the following bugs:
-
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)
All users of xinetd are advised to upgrade to this updated package, which fixes these bugs.
Solution
Before applying this update, make sure that all previously-released errata relevant to your system have been applied.
