ID CVE-2006-1242
Summary The ip_push_pending_frames function in Linux 2.4.x and 2.6.x before 2.6.16 increments the IP ID field when sending a RST after receiving unsolicited TCP SYN-ACK packets, which allows remote attackers to conduct an Idle Scan (nmap -sI) attack, which bypasses intended protections against such attacks.

    description The sys_mbind() function did not properly verify the validity of the 'maxnod' argument. A local user could exploit this to trigger a buffer overflow, which caused a kernel crash. (CVE-2006-0557) The SELinux module did not correctly handle the tracer SID when a process was already being traced. A local attacker could exploit this to cause a kernel crash. (CVE-2006-1052) Al Viro discovered a local Denial of Service in the sysfs write buffer handling. By writing a block with a length exactly equal to the processor's page size to any writable file in /sys, a local attacker could cause a kernel crash. (CVE-2006-1055) John Blackwood discovered a race condition with single-step debugging multiple processes at the same time. A local attacker could exploit this to crash the system. This only affects the amd64 platform. (CVE-2006-1066) Marco Ivaldi discovered a flaw in the handling of the ID number of IP packets. This number was incremented after receiving unsolicited TCP SYN-ACK packets. A remote attacker could exploit this to conduct port scans with the 'Idle scan' method (nmap -sI), which bypassed intended port scan protections. (CVE-2006-1242) Pavel Kankovsky discovered that the getsockopt() function, when called with an SO_ORIGINAL_DST argument, does not properly clear the returned structure, so that a random piece of kernel memory is exposed to the user. This could potentially reveal sensitive data like passwords or encryption keys. (CVE-2006-1343) A buffer overflow was discovered in the USB Gadget RNDIS implementation. While creating a reply message, the driver did not allocate enough memory for the reply structure. A remote attacker could exploit this to cause a kernel crash. (CVE-2006-1368) Alexandra Kossovsky discovered an invalid memory access in the ip_route_input() function. By using the 'ip' command in a particular way to retrieve multicast routes, a local attacker could exploit this to crash the kernel. (CVE-2006-1525). 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.

    description Several local and remote vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service or the execution of arbitrary code. The Common Vulnerabilities and Exposures project identifies the following problems : - CVE-2005-3359 Franz Filz discovered that some socket calls permit causing inconsistent reference counts on loadable modules, which allows local users to cause a denial of service. - CVE-2006-0038 'Solar Designer' discovered that arithmetic computations in netfilter's do_replace() function can lead to a buffer overflow and the execution of arbitrary code. However, the operation requires CAP_NET_ADMIN privileges, which is only an issue in virtualization systems or fine grained access control systems. - CVE-2006-0039 'Solar Designer' discovered a race condition in netfilter's do_add_counters() function, which allows information disclosure of kernel memory by exploiting a race condition. Likewise, it requires CAP_NET_ADMIN privileges. - CVE-2006-0456 David Howells discovered that the s390 assembly version of the strnlen_user() function incorrectly returns some string size values. - CVE-2006-0554 It was discovered that the ftruncate() function of XFS can expose unallocated blocks, which allows information disclosure of previously deleted files. - CVE-2006-0555 It was discovered that some NFS file operations on handles mounted with O_DIRECT can force the kernel into a crash. - CVE-2006-0557 It was discovered that the code to configure memory policies allows tricking the kernel into a crash, thus allowing denial of service. - CVE-2006-0558 It was discovered by Cliff Wickman that perfmon for the IA64 architecture allows users to trigger a BUG() assert, which allows denial of service. - CVE-2006-0741 Intel EM64T systems were discovered to be susceptible to a local DoS due to an endless recursive fault related to a bad ELF entry address. - CVE-2006-0742 Alan and Gareth discovered that the ia64 platform had an incorrectly declared die_if_kernel() function as 'does never return' which could be exploited by a local attacker resulting in a kernel crash. - CVE-2006-0744 The Linux kernel did not properly handle uncanonical return addresses on Intel EM64T CPUs, reporting exceptions in the SYSRET instead of the next instruction, causing the kernel exception handler to run on the user stack with the wrong GS. This may result in a DoS due to a local user changing the frames. - CVE-2006-1056 AMD64 machines (and other 7th and 8th generation AuthenticAMD processors) were found to be vulnerable to sensitive information leakage, due to how they handle saving and restoring the FOP, FIP, and FDP x87 registers in FXSAVE/FXRSTOR when an exception is pending. This allows a process to determine portions of the state of floating point instructions of other processes. - CVE-2006-1242 Marco Ivaldi discovered that there was an unintended information disclosure allowing remote attackers to bypass protections against Idle Scans (nmap -sI) by abusing the ID field of IP packets and bypassing the zero IP ID in DF packet countermeasure. This was a result of the ip_push_pending_frames function improperly incremented the IP ID field when sending a RST after receiving unsolicited TCP SYN-ACK packets. - CVE-2006-1368 Shaun Tancheff discovered a buffer overflow (boundary condition error) in the USB Gadget RNDIS implementation allowing remote attackers to cause a DoS. While creating a reply message, the driver allocated memory for the reply data, but not for the reply structure. The kernel fails to properly bounds-check user-supplied data before copying it to an insufficiently sized memory buffer. Attackers could crash the system, or possibly execute arbitrary machine code. - CVE-2006-1523 Oleg Nesterov reported an unsafe BUG_ON call in signal.c which was introduced by RCU signal handling. The BUG_ON code is protected by siglock while the code in switch_exit_pids() uses tasklist_lock. It may be possible for local users to exploit this to initiate a denial of service attack (DoS). - CVE-2006-1524 Hugh Dickins discovered an issue in the madvise_remove() function wherein file and mmap restrictions are not followed, allowing local users to bypass IPC permissions and replace portions of readonly tmpfs files with zeroes. - CVE-2006-1525 Alexandra Kossovsky reported a NULL pointer dereference condition in ip_route_input() that can be triggered by a local user by requesting a route for a multicast IP address, resulting in a denial of service (panic). - CVE-2006-1857 Vlad Yasevich reported a data validation issue in the SCTP subsystem that may allow a remote user to overflow a buffer using a badly formatted HB-ACK chunk, resulting in a denial of service. - CVE-2006-1858 Vlad Yasevich reported a bug in the bounds checking code in the SCTP subsystem that may allow a remote attacker to trigger a denial of service attack when rounded parameter lengths are used to calculate parameter lengths instead of the actual values. - CVE-2006-1863 Mark Mosely discovered that chroots residing on an CIFS share can be escaped with specially crafted 'cd' sequences. - CVE-2006-1864 Mark Mosely discovered that chroots residing on an SMB share can be escaped with specially crafted 'cd' sequences. - CVE-2006-2271 The 'Mu security team' discovered that carefully crafted ECNE chunks can cause a kernel crash by accessing incorrect state stable entries in the SCTP networking subsystem, which allows denial of service. - CVE-2006-2272 The 'Mu security team' discovered that fragmented SCTP control chunks can trigger kernel panics, which allows for denial of service attacks. - CVE-2006-2274 It was discovered that SCTP packets with two initial bundled data packets can lead to infinite recursion, which allows for denial of service attacks.

    title Debian DSA-1103-1 : kernel-source-2.6.8 - several vulnerabilities
  • NASL family Mandriva Local Security Checks
    NASL id MANDRAKE_MDKSA-2006-086.NASL
    description A number of vulnerabilities were discovered and corrected in the Linux 2.6 kernel : Prior to Linux kernel 2.6.16.5, the kernel does not properly handle uncanonical return addresses on Intel EM64T CPUs which causes the kernel exception handler to run on the user stack with the wrong GS (CVE-2006-0744). The selinux_ptrace logic hooks in SELinux for 2.6.6 allow local users with ptrace permissions to change the tracer SID to an SID of another process (CVE-2006-1052). Prior to 2.6.16, the ip_push_pending_frames function increments the IP ID field when sending a RST after receiving unsolicited TCP SYN-ACK packets, which allows a remote attacker to conduct an idle scan attack, bypassing any intended protection against such an attack (CVE-2006-1242). In kernel 2.6.16.1 and some earlier versions, the sys_add_key function in the keyring code allows local users to cause a DoS (OOPS) via keyctl requests that add a key to a user key instead of a keyring key, causing an invalid dereference (CVE-2006-1522). Prior to 2.6.16.8, the ip_route_input function allows local users to cause a DoS (panic) via a request for a route for a multicast IP address, which triggers a null dereference (CVE-2006-1525). Prior to 2.6.16.13, the SCTP-netfilter code allows remote attackers to cause a DoS (infinite loop) via unknown vectors that cause an invalid SCTP chunk size to be processed (CVE-2006-1527). Prior to 2.6.16, local users can bypass IPC permissions and modify a read-only attachment of shared memory by using mprotect to give write permission to the attachment (CVE-2006-2071). Prior to 2.6.17, the ECNE chunk handling in SCTP (lksctp) allows remote attackers to cause a DoS (kernel panic) via an unexpected chucnk when the session is in CLOSED state (CVE-2006-2271). Prior to 2.6.17, SCTP (lksctp) allows remote attacker to cause a DoS (kernel panic) via incoming IP fragmented COOKIE_ECHO and HEARTBEAT SCTP control chunks (CVE-2006-2272). In addition to these security fixes, other fixes have been included such as : - fix a scheduler deadlock - Yenta oops fix - ftdi_sio: adds support for iPlus devices - enable kprobes on i386 and x86_64 - avoid a panic on bind mount of autofs owned directory - fix a kernel OOPs when booting with 'console=ttyUSB0' but without a USB-serial dongle plugged in - make dm-mirror not issue invalid resync requests - fix media change detection on scsi removable devices - add support for the realtek 8168 chipset - update hfsplus driver to 2.6.16 state - backport 'Gilgal' support from e1000 7.0.33 - selected ACPI video fixes - update 3w-9xxx to 2.26.02.005 (9550SX support) - fix a deadlock in the ext2 filesystem - fix usbserial use-after-free bug - add i945GM DRI support - S3 resume fixes - add ECS PF22 hda model support - SMP suspend - CPU hotplug - miscellaneous AGP fixes - added sata-suspend patch for 2.6.12 for Napa platform The provided packages are patched to fix these vulnerabilities. All users are encouraged to upgrade to these updated kernels. As well, updated mkinitrd and bootsplash packages are provided to fix minor issues; users should upgrade both packages prior to installing a new kernel. To update your kernel, please follow the directions located at : http://www.mandriva.com/en/security/kernelupdate

The following device drivers have been added or upgraded to new versions : adp94xx -------- 1.0.8 (new) bnx2 ----------- 1.4.38 cciss ---------- 2.4.60.RH1 dcdbas --------- 5.6.0-1 (new) e1000 ---------- 7.0.33-k2 emulex --------- 7.3.6 forcedeth ------ 0.30 ipmi ----------- 35.13 qlogic --------- 7.07.04b6 tg3 ------------ 3.52RH The following security bugs were fixed in this update : - 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 exec() handling of multi-threaded tasks using ptrace() that allowed a local user to cause a denial of service (hang of a user process) (CVE-2005-3107, low) - a difference in 'sysretq' operation of EM64T (as opposed to Opteron) processors that allowed a local user to cause a denial of service (crash) upon return from certain system calls (CVE-2006-0741 and CVE-2006-0744, important) - a flaw in unaligned accesses handling on Intel Itanium processors that allowed a local user to cause a denial of service (crash) (CVE-2006-0742, important) - 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 IPv4 netfilter handling for the unlikely use of SNMP NAT processing that allowed a remote user to cause a denial of service (crash) or potential memory corruption (CVE-2006-2444, moderate) Note: The kernel-unsupported package contains various drivers and modules that are unsupported and therefore might contain security problems that have not been addressed. All Red Hat Enterprise Linux 3 users are advised to upgrade their kernels to the packages associated with their machine architectures and configurations as listed in this erratum.

description The ip_push_pending_frames function in Linux 2.4.x and 2.6.x before 2.6.16 increments the IP ID field when sending a RST after receiving unsolicited TCP SYN-ACK packets, which allows remote attackers to conduct an Idle Scan (nmap -sI) attack, which bypasses intended protections against such attacks.
