Linux : Security Vulnerabilities, CVEs, Published In 2010 (Memory corruption) CVSS score >= 6

The aun_incoming function in net/econet/af_econet.c in the Linux kernel before 2.6.37-rc6, when Econet is enabled, allows remote attackers to cause a denial of service (NULL pointer dereference and OOPS) by sending an Acorn Universal Networking (AUN) packet over UDP.

The do_exit function in kernel/exit.c in the Linux kernel before 2.6.36.2 does not properly handle a KERNEL_DS get_fs value, which allows local users to bypass intended access_ok restrictions, overwrite arbitrary kernel memory locations, and gain privileges by leveraging a (1) BUG, (2) NULL pointer dereference, or (3) page fault, as demonstrated by vectors involving the clear_child_tid feature and the splice system call.

Integer overflow in the ioc_general function in drivers/scsi/gdth.c in the Linux kernel before 2.6.36.1 on 64-bit platforms allows local users to cause a denial of service (memory corruption) or possibly have unspecified other impact via a large argument in an ioctl call.

Multiple integer signedness errors in the TIPC implementation in the Linux kernel before 2.6.36.2 allow local users to gain privileges via a crafted sendmsg call that triggers a heap-based buffer overflow, related to the tipc_msg_build function in net/tipc/msg.c and the verify_iovec function in net/core/iovec.c.

Stack-based buffer overflow in the econet_sendmsg function in net/econet/af_econet.c in the Linux kernel before 2.6.36.2, when an econet address is configured, allows local users to gain privileges by providing a large number of iovec structures.

The sctp_auth_asoc_get_hmac function in net/sctp/auth.c in the Linux kernel before 2.6.36 does not properly validate the hmac_ids array of an SCTP peer, which allows remote attackers to cause a denial of service (memory corruption and panic) via a crafted value in the last element of this array.

Double free vulnerability in the snd_seq_oss_open function in sound/core/seq/oss/seq_oss_init.c in the Linux kernel before 2.6.36-rc4 might allow local users to cause a denial of service or possibly have unspecified other impact via an unsuccessful attempt to open the /dev/sequencer device.

The keyctl_session_to_parent function in security/keys/keyctl.c in the Linux kernel 2.6.35.4 and earlier expects that a certain parent session keyring exists, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a KEYCTL_SESSION_TO_PARENT argument to the keyctl function.

The gfs2_dirent_find_space function in fs/gfs2/dir.c in the Linux kernel before 2.6.35 uses an incorrect size value in calculations associated with sentinel directory entries, which allows local users to cause a denial of service (NULL pointer dereference and panic) and possibly have unspecified other impact by renaming a file in a GFS2 filesystem, related to the gfs2_rename function in fs/gfs2/ops_inode.c.

The pppol2tp_xmit function in drivers/net/pppol2tp.c in the L2TP implementation in the Linux kernel before 2.6.34 does not properly validate certain values associated with an interface, which allows attackers to cause a denial of service (NULL pointer dereference and OOPS) or possibly have unspecified other impact via vectors related to a routing change.

mm/shmem.c in the Linux kernel before 2.6.28-rc3, when strict overcommit is enabled, does not properly handle the export of shmemfs objects by knfsd, which allows attackers to cause a denial of service (NULL pointer dereference and knfsd crash) or possibly have unspecified other impact via unknown vectors.

Race condition in the find_keyring_by_name function in security/keys/keyring.c in the Linux kernel 2.6.34-rc5 and earlier allows local users to cause a denial of service (memory corruption and system crash) or possibly have unspecified other impact via keyctl session commands that trigger access to a dead keyring that is undergoing deletion by the key_cleanup function.

Use-after-free vulnerability in net/ipv4/tcp_input.c in the Linux kernel 2.6 before 2.6.20, when IPV6_RECVPKTINFO is set on a listening socket, allows remote attackers to cause a denial of service (kernel panic) via a SYN packet while the socket is in a listening (TCP_LISTEN) state, which is not properly handled and causes the skb structure to be freed.

Linux kernel 2.6.18 through 2.6.33, and possibly other versions, allows remote attackers to cause a denial of service (memory corruption) via a large number of Bluetooth sockets, related to the size of sysfs files in (1) net/bluetooth/l2cap.c, (2) net/bluetooth/rfcomm/core.c, (3) net/bluetooth/rfcomm/sock.c, and (4) net/bluetooth/sco.c.

The ip6_dst_lookup_tail function in net/ipv6/ip6_output.c in the Linux kernel before 2.6.27 does not properly handle certain circumstances involving an IPv6 TUN network interface and a large number of neighbors, which allows attackers to cause a denial of service (NULL pointer dereference and OOPS) or possibly have unspecified other impact via unknown vectors.

The ipv6_hop_jumbo function in net/ipv6/exthdrs.c in the Linux kernel before 2.6.32.4, when network namespaces are enabled, allows remote attackers to cause a denial of service (NULL pointer dereference) via an invalid IPv6 jumbogram, a related issue to CVE-2007-4567.

Use-after-free vulnerability in the fasync_helper function in fs/fcntl.c in the Linux kernel before 2.6.33-rc4-git1 allows local users to gain privileges via vectors that include enabling O_ASYNC (aka FASYNC or FIOASYNC) on a locked file, and then closing this file.
