13 - kernel-vserver-3.4.52-1.mga2
14 description: |
15 This kernel-vserver update provides the upstream 3.4.52 kernel and fixes
16 the follwing security issues:
17
18 The pciback_enable_msi function in the PCI backend driver
19 (drivers/xen/pciback/conf_space_capability_msi.c) in Xen for the Linux
20 kernel 2.6.18 and 3.8 allows guest OS users with PCI device access to
21 cause a denial of service via a large number of kernel log messages.
22 (CVE-2013-0231 / XSA-43)
23
24 ipv6: ip6_sk_dst_check() must not assume ipv6 dst
25 It's possible to use AF_INET6 sockets and to connect to an IPv4
26 destination. After this, socket dst cache is a pointer to a rtable,
27 not rt6_info. This bug can be exploited by local non-root users
28 to trigger various corruptions/crashes (CVE-2013-2232)
29
30 af_key: fix info leaks in notify messages
31 key_notify_sa_flush() and key_notify_policy_flush() miss to
32 initialize the sadb_msg_reserved member of the broadcasted message
33 and thereby leak 2 bytes of heap memory to listeners (CVE-2013-2234)
34
35 af_key: initialize satype in key_notify_policy_flush()
36 key_notify_policy_flush() miss to nitialize the sadb_msg_satype member
37 of the broadcasted message and thereby leak heap memory to listeners
38 (CVE-2013-2237)
39
40 Heap-based buffer overflow in the iscsi_add_notunderstood_response function
41 in drivers/target/iscsi/iscsi_target_parameters.c in the iSCSI target
42 subsystem in the Linux kernel through 3.9.4 allows remote attackers to
43 cause a denial of service (memory corruption and OOPS) or possibly execute
44 arbitrary code via a long key that is not properly handled during
45 construction of an error-response packet.
46 A reproduction case requires patching open-iscsi to send overly large
47 keys. Performing discovery in a loop will Oops the remote server.
48 (CVE-2013-2850)
49
50 Format string vulnerability in the b43_request_firmware function in
51 drivers/net/wireless/b43/main.c in the Broadcom B43 wireless driver in
52 the Linux kernel through 3.9.4 allows local users to gain privileges by
53 leveraging root access and including format string specifiers in an
54 fwpostfix modprobe parameter, leading to improper construction of an
55 error message. (CVE-2013-2852)
56
57 Other fixes:
58 Fix up alx AR8161 breakage (mga #10079)
