atm/solos-pci: Don't flap VCs when carrier state changes

2011-04-14T20:02:39+00:00

commit c031235b395433350f25943b7580a5e343c7b7b2 upstream. Don't flap VCs when carrier state changes; higher-level protocols can detect loss of connectivity and act accordingly. This is more consistent with how other network interfaces work. We no longer use release_vccs() so we can delete it. release_vccs() was duplicated from net/atm/common.c; make the corresponding function exported, since other code duplicates it and could leverage it if it were public.

netfilter: h323: bug in parsing of ASN1 SEQOF field

2011-04-14T20:02:37+00:00

commit b4232a22776aa5d063f890d21ca69870dbbe431b upstream. Static analyzer of clang found a dead store which appears to be a bug in reading count of items in SEQOF field, only the lower byte of word is stored. This may lead to corrupted read and communication shutdown. The bug has been in the module since it's first inclusion into linux kernel. [Patrick: the bug is real, but without practical consequence since the largest amount of sequence-of members we parse is 30.] Signed-off-by: David Sterba Signed-off-by: Patrick McHardy Signed-off-by: Greg Kroah-Hartman

econet: 4 byte infoleak to the network

2011-04-14T20:02:37+00:00

commit 67c5c6cb8129c595f21e88254a3fc6b3b841ae8e upstream. struct aunhdr has 4 padding bytes between 'pad' and 'handle' fields on x86_64. These bytes are not initialized in the variable 'ah' before sending 'ah' to the network. This leads to 4 bytes kernel stack infoleak. This bug was introduced before the git epoch.

ipv6: netfilter: ip6_tables: fix infoleak to userspace

2011-04-14T20:02:33+00:00

commit 6a8ab060779779de8aea92ce3337ca348f973f54 upstream. Structures ip6t_replace, compat_ip6t_replace, and xt_get_revision are copied from userspace. Fields of these structs that are zero-terminated strings are not checked. When they are used as argument to a format string containing "%s" in request_module(), some sensitive information is leaked to userspace via argument of spawned modprobe process. The first bug was introduced before the git epoch; the second was introduced in 3bc3fe5e (v2.6.25-rc1); the third is introduced by 6b7d31fc (v2.6.15-rc1). To trigger the bug one should have CAP_NET_ADMIN. Signed-off-by: Vasiliy Kulikov Signed-off-by: Patrick McHardy Signed-off-by: Greg Kroah-Hartman

netfilter: ipt_CLUSTERIP: fix buffer overflow

2011-04-14T20:02:32+00:00

commit 961ed183a9fd080cf306c659b8736007e44065a5 upstream. 'buffer' string is copied from userspace. It is not checked whether it is zero terminated. This may lead to overflow inside of simple_strtoul(). Changli Gao suggested to copy not more than user supplied 'size' bytes. It was introduced before the git epoch. Files "ipt_CLUSTERIP/*" are root writable only by default, however, on some setups permissions might be relaxed to e.g. network admin user.

netfilter: xtables: fix reentrancy

2011-04-14T20:02:31+00:00

commit db856674ac69e31946e56085239757cca3f7655f upstream. commit f3c5c1bfd4308 (make ip_tables reentrant) introduced a race in handling the stackptr restore, at the end of ipt_do_table() We should do it before the call to xt_info_rdunlock_bh(), or we allow cpu preemption and another cpu overwrites stackptr of original one. A second fix is to change the underflow test to check the origptr value instead of 0 to detect underflow, or else we allow a jump from different hooks.
