COMPLETE Summary
Heap-based buffer overflow in the is_gpt_valid function in fs/partitions/efi.c in the Linux kernel 2.6.38 and earlier allows physically proximate attackers to cause a denial of service (OOPS) or possibly have unspecified other impact via a crafted size of the EFI GUID partition-table header on removable media.
Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Buffer Overflow via Environment Variables This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
- Overflow Buffers Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
- Client-side Injection-induced Buffer Overflow This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
- Filter Failure through Buffer Overflow In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
- MIME Conversion An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

The following security issues were fixed : - Multiple integer overflows in the next_pidmap function in kernel/pid.c in the Linux kernel allowed local users to cause a denial of service (system crash) via a crafted (1) getdents or (2) readdir system call. (CVE-2011-1593) - Only half of the fix for this vulnerability was only applied, the fix was completed now. Original text: drivers/net/e1000/e1000_main.c in the e1000 driver in the Linux kernel handled Ethernet frames that exceed the MTU by processing certain trailing payload data as if it were a complete frame, which allows remote attackers to bypass packet filters via a large packet with a crafted payload. (CVE-2009-4536) - Boundschecking was missing in AARESOLVE_OFFSET in the SCTP protocol, which allowed local attackers to overwrite kernel memory and so escalate privileges or crash the kernel. (CVE-2011-1573) - Heap-based buffer overflow in the ldm_frag_add function in fs/partitions/ldm.c in the Linux kernel might have allowed local users to gain privileges or obtain sensitive information via a crafted LDM partition table. (CVE-2011-1017) - When using a setuid root mount.cifs, local users could hijack password protected mounted CIFS shares of other local users. (CVE-2011-1585) - Kernel information via the TPM devices could by used by local attackers to read kernel memory. (CVE-2011-1160) - The Linux kernel automatically evaluated partition tables of storage devices. The code for evaluating EFI GUID partitions (in fs/partitions/efi.c) contained a bug that causes a kernel oops on certain corrupted GUID partition tables, which might be used by local attackers to crash the kernel or potentially execute code. (CVE-2011-1577) - In the IrDA module, length fields provided by a peer for names and attributes may be longer than the destination array sizes and were not checked, this allowed local attackers (close to the irda port) to potentially corrupt memory. (CVE-2011-1180) - A system out of memory condition (denial of service) could be triggered with a large socket backlog, exploitable by local users. This has been addressed by backlog limiting. (CVE-2010-4251) - The Radeon GPU drivers in the Linux kernel did not properly validate data related to the AA resolve registers, which allowed local users to write to arbitrary memory locations associated with (1) Video RAM (aka VRAM) or (2) the Graphics Translation Table (GTT) via crafted values. (CVE-2011-1016) - When parsing the FAC_NATIONAL_DIGIS facilities field, it was possible for a remote host to provide more digipeaters than expected, resulting in heap corruption. (CVE-2011-1493) - Local attackers could send signals to their programs that looked like coming from the kernel, potentially gaining privileges in the context of setuid programs. (CVE-2011-1182) - The code for evaluating LDM partitions (in fs/partitions/ldm.c) contained bugs that could crash the kernel for certain corrupted LDM partitions. (CVE-2011-1017 / CVE-2011-1012) - The code for evaluating Mac partitions (in fs/partitions/mac.c) contained a bug that could crash the kernel for certain corrupted Mac partitions. (CVE-2011-1010) - The code for evaluating OSF partitions (in fs/partitions/osf.c) contained a bug that leaks data from kernel heap memory to userspace for certain corrupted OSF partitions. (CVE-2011-1163) - Specially crafted requests may be written to /dev/sequencer resulting in an underflow when calculating a size for a copy_from_user() operation in the driver for MIDI interfaces. On x86, this just returns an error, but it could have caused memory corruption on other architectures. Other malformed requests could have resulted in the use of uninitialized variables. (CVE-2011-1476) - Due to a failure to validate user-supplied indexes in the driver for Yamaha YM3812 and OPL-3 chips, a specially crafted ioctl request could have been sent to /dev/sequencer, resulting in reading and writing beyond the bounds of heap buffers, and potentially allowing privilege escalation. (CVE-2011-1477) - A information leak in the XFS geometry calls could be used by local attackers to gain access to kernel information. (CVE-2011-0191) - The sctp_rcv_ootb function in the SCTP implementation in the Linux kernel allowed remote attackers to cause a denial of service (infinite loop) via (1) an Out Of The Blue (OOTB) chunk or (2) a chunk of zero length.

Following security issues have been fixed: CVE-2011-1493: In the rose networking stack, when parsing the FAC_NATIONAL_DIGIS facilities field, it was possible for a remote host to provide more digipeaters than expected, resulting in heap corruption. Check against ROSE_MAX_DIGIS to prevent overflows, and abort facilities parsing on failure. CVE-2011-1182: Local attackers could send signals to their programs that looked like coming from the kernel, potentially gaining privileges in the context of setuid programs. CVE-2011-1478: An issue in the core GRO code where an skb belonging to an unknown VLAN is reused could result in a NULL pointer dereference. CVE-2011-1476: Specially crafted requests may be written to /dev/sequencer resulting in an underflow when calculating a size for a copy_from_user() operation in the driver for MIDI interfaces. On x86, this just returns an error, but it could have caused memory corruption on other architectures. Other malformed requests could have resulted in the use of uninitialized variables. CVE-2011-1477: Due to a failure to validate user-supplied indexes in the driver for Yamaha YM3812 and OPL-3 chips, a specially crafted ioctl request could have been sent to /dev/sequencer, resulting in reading and writing beyond the bounds of heap buffers, and potentially allowing privilege escalation.

Following security issues have been fixed: CVE-2011-2495: The /proc/PID/io interface could be used by local attackers to gain information on other processes like number of password characters typed or similar. CVE-2011-2484: The add_del_listener function in kernel/taskstats.c in the Linux kernel did not prevent multiple registrations of exit handlers, which allowed local users to cause a denial of service (memory and CPU consumption), and bypass the OOM Killer, via a crafted application. CVE-2011-2491: A local unprivileged user able to access a NFS filesystem could use file locking to deadlock parts of an nfs server under some circumstance. CVE-2011-2496: The normal mmap paths all avoid creating a mapping where the pgoff inside the mapping could wrap around due to overflow. However, an expanding mremap() can take such a non-wrapping mapping and make it bigger and cause a wrapping condition. CVE-2011-1017,CVE-2011-2182: The code for evaluating LDM partitions (in fs/partitions/ldm.c) contained bugs that could crash the kernel for certain corrupted LDM partitions. CVE-2011-1479: A regression in inotify fix for a memory leak could lead to a double free corruption which could crash the system. CVE-2011-1593: Multiple integer overflows in the next_pidmap function in kernel/pid.c in the Linux kernel allowed local users to cause a denial of service (system crash) via a crafted (1) getdents or (2) readdir system call. CVE-2011-1020: The proc filesystem implementation in the Linux kernel did not restrict access to the /proc directory tree of a process after this process performs an exec of a setuid program, which allowed local users to obtain sensitive information or cause a denial of service via open, lseek, read, and write system calls. CVE-2011-1585: When using a setuid root mount.cifs, local users could hijack password protected mounted CIFS shares of other local users. CVE-2011-1160: Kernel information via the TPM devices could by used by local attackers to read kernel memory. CVE-2011-1577: The Linux kernel automatically evaluated partition tables of storage devices. The code for evaluating EFI GUID partitions (in fs/partitions/efi.c) contained a bug that causes a kernel oops on certain corrupted GUID partition tables, which might be used by local attackers to crash the kernel or potentially execute code. CVE-2011-1180: In the IrDA module, length fields provided by a peer for names and attributes may be longer than the destination array sizes and were not checked, this allowed local attackers (close to the irda port) to potentially corrupt memory. CVE-2011-1016: The Radeon GPU drivers in the Linux kernel did not properly validate data related to the AA resolve registers, which allowed local users to write to arbitrary memory locations associated with (1) Video RAM (aka VRAM) or (2) the Graphics Translation Table (GTT) via crafted values. CVE-2011-1013: A signedness issue in the drm ioctl handling could be used by local attackers to potentially overflow kernel buffers and execute code. last seen 2020-06-01 modified 2020-06-02 plugin id 75555 published 2014-06-13 reporter This script is Copyright (C) 2014-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/75555 title openSUSE Security Update : kernel (openSUSE-SU-2011:0861-1) NASL family SuSE Local Security Checks NASL id SUSE_KERNEL-7516.NASL description This kernel update for the SUSE Linux Enterprise 10 SP4 kernel fixes several security issues and bugs. The following security issues were fixed : - The code for evaluating LDM partitions (in fs/partitions/ldm.c) contained bugs that could crash the kernel for certain corrupted LDM partitions. (CVE-2011-1017 / CVE-2011-1012) - Boundschecking was missing in AARESOLVE_OFFSET, which allowed local attackers to overwrite kernel memory and so escalate privileges or crash the kernel. (CVE-2011-1573) - When using a setuid root mount.cifs, local users could hijack password protected mounted CIFS shares of other local users. (CVE-2011-1585) - Kernel information via the TPM devices could by used by local attackers to read kernel memory. (CVE-2011-1160) - The Linux kernel automatically evaluated partition tables of storage devices. The code for evaluating EFI GUID partitions (in fs/partitions/efi.c) contained a bug that causes a kernel oops on certain corrupted GUID partition tables, which might be used by local attackers to crash the kernel or potentially execute code. (CVE-2011-1577) - In the IrDA module, length fields provided by a peer for names and attributes may be longer than the destination array sizes and were not checked, this allowed local attackers (close to the irda port) to potentially corrupt memory. (CVE-2011-1180) - A system out of memory condition (denial of service) could be triggered with a large socket backlog, exploitable by local users. This has been addressed by backlog limiting. (CVE-2010-4251) - The Radeon GPU drivers in the Linux kernel did not properly validate data related to the AA resolve registers, which allowed local users to write to arbitrary memory locations associated with (1) Video RAM (aka VRAM) or (2) the Graphics Translation Table (GTT) via crafted values. (CVE-2011-1016) - When parsing the FAC_NATIONAL_DIGIS facilities field, it was possible for a remote host to provide more digipeaters than expected, resulting in heap corruption. (CVE-2011-1493) - Local attackers could send signals to their programs that looked like coming from the kernel, potentially gaining privileges in the context of setuid programs. (CVE-2011-1182) - The code for evaluating Mac partitions (in fs/partitions/mac.c) contained a bug that could crash the kernel for certain corrupted Mac partitions. (CVE-2011-1010) - The code for evaluating OSF partitions (in fs/partitions/osf.c) contained a bug that leaks data from kernel heap memory to userspace for certain corrupted OSF partitions. (CVE-2011-1163) - Specially crafted requests may be written to /dev/sequencer resulting in an underflow when calculating a size for a copy_from_user() operation in the driver for MIDI interfaces. On x86, this just returns an error, but it could have caused memory corruption on other architectures. Other malformed requests could have resulted in the use of uninitialized variables. (CVE-2011-1476) - Due to a failure to validate user-supplied indexes in the driver for Yamaha YM3812 and OPL-3 chips, a specially crafted ioctl request could have been sent to /dev/sequencer, resulting in reading and writing beyond the bounds of heap buffers, and potentially allowing privilege escalation. (CVE-2011-1477) - A information leak in the XFS geometry calls could be used by local attackers to gain access to kernel information. (CVE-2011-0191) - The sctp_rcv_ootb function in the SCTP implementation in the Linux kernel allowed remote attackers to cause a denial of service (infinite loop) via (1) an Out Of The Blue (OOTB) chunk or (2) a chunk of zero length.
