linux linux kernel 2.6.33.3 vulnerabilities and exploits

(subscribe to this query)

net/ipv6/netfilter/nf_conntrack_reasm.c in the Linux kernel prior to 2.6.34, when the nf_conntrack_ipv6 module is enabled, allows remote malicious users to cause a denial of service (NULL pointer dereference and system crash) via certain types of fragmented IPv6 packets.

The veth (aka virtual Ethernet) driver in the Linux kernel prior to 2.6.34 does not properly manage skbs during congestion, which allows remote malicious users to cause a denial of service (system crash) by leveraging lack of skb consumption in conjunction with a double-free erro...

The sctp_process_unk_param function in net/sctp/sm_make_chunk.c in the Linux kernel 2.6.33.3 and previous versions, when SCTP is enabled, allows remote malicious users to cause a denial of service (system crash) via an SCTPChunkInit packet containing multiple invalid parameters t...

Integer overflow in the ext4_ext_get_blocks function in fs/ext4/extents.c in the Linux kernel prior to 2.6.34 allows local users to cause a denial of service (BUG and system crash) via a write operation on the last block of a large file, followed by a sync operation.

The do_task_stat function in fs/proc/array.c in the Linux kernel prior to 2.6.39-rc1 does not perform an expected uid check, which makes it easier for local users to defeat the ASLR protection mechanism by reading the start_code and end_code fields in the /proc/#####/stat file fo...

net/ipv4/netfilter/arp_tables.c in the IPv4 implementation in the Linux kernel prior to 2.6.39 does not place the expected '\0' character at the end of string data in the values of certain structure members, which allows local users to obtain potentially sensitive infor...

net/ipv4/netfilter/ip_tables.c in the IPv4 implementation in the Linux kernel prior to 2.6.39 does not place the expected '\0' character at the end of string data in the values of certain structure members, which allows local users to obtain potentially sensitive inform...
