Synopsis
The remote Oracle Linux host is missing one or more security updates.Description
The remote Oracle Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2012-1580 advisory.- The ext4_fill_flex_info function in fs/ext4/super.c in the Linux kernel before 3.2.2, on the x86 platform and unspecified other platforms, allows user-assisted remote attackers to trigger inconsistent filesystem- groups data and possibly cause a denial of service via a malformed ext4 filesystem containing a super block with a large FLEX_BG group size (aka s_log_groups_per_flex value). NOTE: this vulnerability exists because of an incomplete fix for CVE-2009-4307. (CVE-2012-2100)
- The __nfs4_get_acl_uncached function in fs/nfs/nfs4proc.c in the NFSv4 implementation in the Linux kernel before 3.3.2 uses an incorrect length variable during a copy operation, which allows remote NFS servers to cause a denial of service (OOPS) by sending an excessive number of bitmap words in an FATTR4_ACL reply.
NOTE: this vulnerability exists because of an incomplete fix for CVE-2011-4131. (CVE-2012-2375)
- The ip6_frag_queue function in net/ipv6/reassembly.c in the Linux kernel before 2.6.36 allows remote attackers to bypass intended network restrictions via overlapping IPv6 fragments. (CVE-2012-4444)
- The tcp_illinois_info function in net/ipv4/tcp_illinois.c in the Linux kernel before 3.4.19, when the net.ipv4.tcp_congestion_control illinois setting is enabled, allows local users to cause a denial of service (divide-by-zero error and OOPS) by reading TCP stats. (CVE-2012-4565)
- The online_pages function in mm/memory_hotplug.c in the Linux kernel before 3.6 allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact in opportunistic circumstances by using memory that was hot-added by an administrator.
(CVE-2012-5517)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
