Mandriva Linux Security Advisory MDKSA-2006:150

Package : kernel
Date : August 25, 2006
Affected: Corporate 3.0, Multi Network Firewall 2.0

Problem Description:

A number of vulnerabilities were discovered and corrected in the Linux
2.6 kernel:

Prior to, the kerenl allowed local users to obtain sensitive
information via a crafted XFS ftruncate call (CVE-2006-0554).

Prior to, the kernel did not properly handle uncanonical
return addresses on Intel EM64T CPUs causing the kernel exception
handler to run on the user stack with the wrong GS (CVE-2006-0744).

ip_conntrack_core.c in the 2.6 kernel, and possibly
nf_conntrack_l3proto_ipv4.c did not clear sockaddr_in.sin_zero before
returning IPv4 socket names from the getsockopt function with
SO_ORIGINAL_DST, which could allow local users to obtain portions of
potentially sensitive memory (CVE-2006-1343).

Prior to, the a buffer overflow in SCTP in the kernel allowed
remote attackers to cause a Denial of Service (crash) and possibly
execute arbitrary code via a malformed HB-ACK chunk (CVE-2006-1857).

Prior to, SCTP in the kernel allowed remote attackers to
cause a DoS (crash) and possibly execute arbitrary code via a chunk
length that is inconsistent with the actual length of provided
parameters (CVE-2006-1858).

Prior to 2.6.16, a directory traversal vulnerability in CIFS could
allow a local user to escape chroot restrictions for an SMB-mounted
filesystem via "..\\\\" sequences (CVE-2006-1863).

Prior to 2.6.16, a directory traversal vulnerability in smbfs could
allow a local user to escape chroot restrictions for an SMB-mounted
filesystem via "..\\\\" sequences (CVE-2006-1864).

Prior to 2.6.17, Linux SCTP allowed a remote attacker to cause a DoS
(infinite recursion and crash) via a packet that contains two or more
DATA fragments, which caused an skb pointer to refer back to itself
when the full message is reassembled, leading to an infinite recursion
in the sctp_skb_pull function (CVE-2006-2274).

The dvd_read_bca function in the DVD handling code assigns the wrong
value to a length variable, which could allow local users to execute
arbitrary code via a crafted USB storage device that triggers a buffer
overflow (CVE-2006-2935).

Prior to 2.6.17, the ftdi_sio driver could allow local users to cause
a DoS (memory consumption) by writing more data to the serial port than
the hardware can handle, causing the data to be queued (CVE-2006-2936).

The 2.6 kernel, when using both NFS and EXT3, allowed remote attackers
to cause a DoS (file system panic) via a crafted UDP packet with a V2
lookup procedure that specifies a bad file handle (inode number),
triggering an error and causing an exported directory to be remounted
read-only (CVE-2006-3468).

The 2.6 kernel's SCTP was found to cause system crashes and allow for
the possibility of local privilege escalation due to a bug in the
get_user_iov_size() function that doesn't properly handle overflow when
calculating the length of iovec (CVE-2006-3745).

The provided packages are patched to fix these vulnerabilities. All
users are encouraged to upgrade to these updated kernels immediately
and reboot to effect the fixes.
