The remote Scientific Linux host is missing one or more security
This update fixes the following security issues :
- It was found that a previous update did not correctly
fix the CVE-2011-4131 issue. A malicious Network File
System version 4 (NFSv4) server could return a crafted
reply to a GETACL request, causing a denial of service
on the client. (CVE-2012-2375, Moderate)
- A divide-by-zero flaw was found in the TCP Illinois
congestion control algorithm implementation in the Linux
kernel. If the TCP Illinois congestion control algorithm
were in use (the sysctl net.ipv4.tcp_congestion_control
variable set to 'illinois'), a local, unprivileged user
could trigger this flaw and cause a denial of service.
- A NULL pointer dereference flaw was found in the way a
new node's hot added memory was propagated to other
nodes' zonelists. By utilizing this newly added memory
from one of the remaining nodes, a local, unprivileged
user could use this flaw to cause a denial of service.
- It was found that the initial release of Scientific
Linux 6 did not correctly fix the CVE-2009-4307 issue, a
divide-by-zero flaw in the ext4 file system code. A
local, unprivileged user with the ability to mount an
ext4 file system could use this flaw to cause a denial
of service. (CVE-2012-2100, Low)
- A flaw was found in the way the Linux kernel's IPv6
implementation handled overlapping, fragmented IPv6
packets. A remote attacker could potentially use this
flaw to bypass protection mechanisms (such as a firewall
or intrusion detection system (IDS)) when sending
network packets to a target system. (CVE-2012-4444, Low)
The system must be rebooted for this update to take effect.
