The remote host is missing updates announced in
advisory RHSA-2006:0575.
This update includes fixes for the security issues:
* a flaw in the USB devio handling of device removal that allowed a
local user to cause a denial of service (crash) (CVE-2005-3055,
moderate)
* a flaw in the ACL handling of nfsd that allowed a remote user to
bypass ACLs for readonly mounted NFS file systems (CVE-2005-3623,
moderate)
* a flaw in the netfilter handling that allowed a local user with
CAP_NET_ADMIN rights to cause a buffer overflow (CVE-2006-0038, low)
* a flaw in the IBM S/390 and IBM zSeries strnlen_user() function that
allowed a local user to cause a denial of service (crash) or to retrieve
random kernel data (CVE-2006-0456, important)
* a flaw in the keyctl functions that allowed a local user to cause a
denial of service (crash) or to read sensitive kernel memory
(CVE-2006-0457, important)
* a flaw in unaligned accesses handling on Itanium processors that
allowed a local user to cause a denial of service (crash)
(CVE-2006-0742, important)
* a flaw in SELinux ptrace logic that allowed a local user with ptrace
permissions to change the tracer SID to a SID of another process
(CVE-2006-1052, moderate)
* an info leak on AMD-based x86 and x86_64 systems that allowed a local
user to retrieve the floating point exception state of a process run by a
different user (CVE-2006-1056, important)
* a flaw in IPv4 packet output handling that allowed a remote user to
bypass the zero IP ID countermeasure on systems with a disabled firewall
(CVE-2006-1242, low)
* a minor info leak in socket option handling in the network code
(CVE-2006-1343, low)
* a flaw in the HB-ACK chunk handling of SCTP that allowed a remote user to
cause a denial of service (crash) (CVE-2006-1857, moderate)
* a flaw in the SCTP implementation that allowed a remote user to cause a
denial of service (deadlock) (CVE-2006-2275, moderate)
* a flaw in the socket buffer handling that allowed a remote user to cause
a denial of service (panic) (CVE-2006-2446, important)
* a flaw in the signal handling access checking on PowerPC that allowed a
local user to cause a denial of service (crash) or read arbitrary kernel
memory on 64-bit systems (CVE-2006-2448, important)
* a flaw in the netfilter SCTP module when receiving a chunkless packet
that allowed a remote user to cause a denial of service (crash)
(CVE-2006-2934, important)
