Summary

Linux kernel before 2.6.16.21 and 2.6.17, when running on PowerPC, does not perform certain required access_ok checks, which allows local users to read arbitrary kernel memory on 64-bit systems (signal_64.c) and cause a denial of service (crash) and possibly read kernel memory on 32-bit systems (signal_32.c).

    descriptionA race condition was discovered in the do_add_counters() functions. Processes which do not run with full root privileges, but have the CAP_NET_ADMIN capability can exploit this to crash the machine or read a random piece of kernel memory. In Ubuntu there are no packages that are affected by this, so this can only be an issue for you if you use third-party software that uses Linux capabilities. (CVE-2006-0039) John Stultz discovered a faulty BUG_ON trigger in the handling of POSIX timers. A local attacker could exploit this to trigger a kernel oops and crash the machine. (CVE-2006-2445) Dave Jones discovered that the PowerPC kernel did not perform certain required access_ok() checks. A local user could exploit this to read arbitrary kernel memory and crash the kernel on 64-bit systems, and possibly read arbitrary kernel memory on 32-bit systems. (CVE-2006-2448) A design flaw was discovered in the prctl(PR_SET_DUMPABLE, ...) system call, which allowed a local user to have core dumps created in a directory he could not normally write to. This could be exploited to drain available disk space on system partitions, or, under some circumstances, to execute arbitrary code with full root privileges. This flaw only affects Ubuntu 6.06 LTS. (CVE-2006-2451) In addition, the Ubuntu 6.06 LTS update fixes a range of bugs. Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    descriptionUpdated kernel packages are now available as part of ongoing support and maintenance of Red Hat Enterprise Linux version 4. This update has been rated as having important security impact by the Red Hat Security Response Team. The Linux kernel handles the basic functions of the operating system. This is the fourth regular update to Red Hat Enterprise Linux 4. New features introduced in this update include : * Device Mapper mirroring support * IDE diskdump support * x86, AMD64 and Intel EM64T: Multi-core scheduler support enhancements * Itanium: perfmon support for Montecito * much improved support for IBM x460 * AMD PowerNow! patches to support Opteron Rev G * Vmalloc support > 64MB The following device drivers have been upgraded to new versions : ipmi: 33.11 to 33.13 ib_mthca: 0.06 to 0.08 bnx2: 1.4.30 to 1.4.38 bonding: 2.6.1 to 2.6.3 e100: 3.4.8-k2-NAPI to 3.5.10-k2-NAPI e1000: 6.1.16-k3-NAPI to 7.0.33-k2-NAPI sky2: 0.13 to 1.1 tg3: 3.43-rh to 3.52-rh ipw2100: 1.1.0 to git-1.1.4 ipw2200: 1.0.0 to git-1.0.10 3w-9xxx: 2.26.02.001 to 2.26.04.010 ips: 7.10.18 to 7.12.02 iscsi_sfnet: 4:0.1.11-2 to 4:0.1.11-3 lpfc: 0:8.0.16.18 to 0:8.0.16.27 megaraid_sas: 00.00.02.00 to 00.00.02.03-RH1 qla2xxx: 8.01.02-d4 to 8.01.04-d7 qla6312: 8.01.02-d4 to 8.01.04-d7 sata_promise: 1.03 to 1.04 sata_vsc: 1.1 to 1.2 ibmvscsic: 1.5.5 to 1.5.6 ipr: 2.0.11.1 to 2.0.11.2 Added drivers : dcdbas: 5.6.0-2 sata_mv: 0.6 sata_qstor: 0.05 sata_uli: 0.5 skge: 1.1 stex: 2.9.0.13 pdc_adma: 0.03 This update includes fixes for the security issues : * a flaw in the USB devio handling of device removal that allowed a local user to cause a denial of service (crash) (CVE-2005-3055, moderate) * a flaw in the ACL handling of nfsd that allowed a remote user to bypass ACLs for readonly mounted NFS file systems (CVE-2005-3623, moderate) * a flaw in the netfilter handling that allowed a local user with CAP_NET_ADMIN rights to cause a buffer overflow (CVE-2006-0038, low) * a flaw in the IBM S/390 and IBM zSeries strnlen_user() function that allowed a local user to cause a denial of service (crash) or to retrieve random kernel data (CVE-2006-0456, important) * a flaw in the keyctl functions that allowed a local user to cause a denial of service (crash) or to read sensitive kernel memory (CVE-2006-0457, important) * a flaw in unaligned accesses handling on Itanium processors that allowed a local user to cause a denial of service (crash) (CVE-2006-0742, important) * a flaw in SELinux ptrace logic that allowed a local user with ptrace permissions to change the tracer SID to a SID of another process (CVE-2006-1052, moderate) * an info leak on AMD-based x86 and x86_64 systems that allowed a local user to retrieve the floating point exception state of a process run by a different user (CVE-2006-1056, important) * a flaw in IPv4 packet output handling that allowed a remote user to bypass the zero IP ID countermeasure on systems with a disabled firewall (CVE-2006-1242, low) * a minor info leak in socket option handling in the network code (CVE-2006-1343, low) * a flaw in the HB-ACK chunk handling of SCTP that allowed a remote user to cause a denial of service (crash) (CVE-2006-1857, moderate) * a flaw in the SCTP implementation that allowed a remote user to cause a denial of service (deadlock) (CVE-2006-2275, moderate) * a flaw in the socket buffer handling that allowed a remote user to cause a denial of service (panic) (CVE-2006-2446, important) * a flaw in the signal handling access checking on PowerPC that allowed a local user to cause a denial of service (crash) or read arbitrary kernel memory on 64-bit systems (CVE-2006-2448, important) * a flaw in the netfilter SCTP module when receiving a chunkless packet that allowed a remote user to cause a denial of service (crash) (CVE-2006-2934, important) There were several bug fixes in various parts of the kernel.
