The remote Scientific Linux host is missing one or more security
This update fixes the following security issue :
- A flaw was found in the sctp_icmp_proto_unreachable()
function in the Linux kernel's Stream Control
Transmission Protocol (SCTP) implementation. A remote
attacker could use this flaw to cause a denial of
service. (CVE-2010-4526, Important)
This update also fixes the following bugs :
- Due to an off-by-one error, gfs2_grow failed to take the
very last 'rgrp' parameter into account when adding up
the new free space. With this update, the GFS2 kernel
properly counts all the new resource groups and fixes
the 'statfs' file correctly. (BZ#666792)
- Prior to this update, a multi-threaded application,
which invoked popen(3) internally, could cause a thread
stall by FILE lock corruption. The application program
waited for a FILE lock in glibc, but the lock seemed to
be corrupted, which was caused by a race condition in
the COW (Copy On Write) logic. With this update, the
race condition was corrected and FILE lock corruption no
longer occurs. (BZ#667050)
- If an error occurred during I/O, the SCSI driver reset
the 'megaraid_sas' controller to restore it to normal
state. However, on Scientific Linux 5, the waiting time
to allow a full reset completion for the 'megaraid_sas'
controller was too short. The driver incorrectly
recognized the controller as stalled, and, as a result,
the system stalled as well. With this update, more time
is given to the controller to properly restart, thus,
the controller operates as expected after being reset.
The system must be rebooted for this update to take effect.
