Vulnerabilities > CVE-2015-8324 - Unspecified vulnerability in Linux Kernel
Attack vector
PHYSICAL Attack complexity
LOW Privileges required
NONE Confidentiality impact
NONE Integrity impact
NONE Availability impact
HIGH Summary
The ext4 implementation in the Linux kernel before 2.6.34 does not properly track the initialization of certain data structures, which allows physically proximate attackers to cause a denial of service (NULL pointer dereference and panic) via a crafted USB device, related to the ext4_fill_super function.

NASL family Debian Local Security Checks NASL id DEBIAN_DLA-360.NASL description This update fixes the CVEs described below. CVE-2013-7446 Dmitry Vyukov discovered that a particular sequence of valid operations on local (AF_UNIX) sockets can result in a use-after-free. This may be used to cause a denial of service (crash) or possibly for privilege escalation. CVE-2015-7799 郭永刚 discovered that a user granted access to /dev/ppp can cause a denial of service (crash) by passing invalid parameters to the PPPIOCSMAXCID ioctl. This also applies to ISDN PPP device nodes. CVE-2015-7833 Sergej Schumilo, Hendrik Schwartke and Ralf Spenneberg discovered a flaw in the processing of certain USB device descriptors in the usbvision driver. An attacker with physical access to the system can use this flaw to crash the system. CVE-2015-7990 It was discovered that the fix for CVE-2015-6937 was incomplete. A race condition when sending a message on unbound socket can still cause a NULL pointer dereference. A remote attacker might be able to cause a denial of service (crash) by sending a crafted packet.

CVE-2015-8324 'Valintinr' reported that an attempt to mount a corrupted ext4 filesystem may result in a kernel panic. A user permitted to mount filesystems could use this flaw to crash the system. For the oldoldstable distribution (squeeze), these problems have been fixed in version 2.6.32-48squeeze17. We recommend that you upgrade your linux-2.6 packages. For the oldstable (wheezy) and stable (jessie) distributions, CVE-2015-7833, CVE-2015-7990 and CVE-2015-8324 have been fixed and the other issues will be fixed soon.

Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es) : * It was found that reporting emulation failures to user space could lead to either a local (CVE-2014-7842) or a L2->L1 (CVE-2010-5313) denial of service. In the case of a local denial of service, an attacker must have access to the MMIO area or be able to access an I/O port. Please note that on certain systems, HPET is mapped to userspace as part of vdso (vvar) and thus an unprivileged user may generate MMIO transactions (and enter the emulator) this way. (CVE-2010-5313, CVE-2014-7842, Moderate) * It was found that the Linux kernel did not properly account file descriptors passed over the unix socket against the process limit. A local user could use this flaw to exhaust all available memory on the system. (CVE-2013-4312, Moderate) * A buffer overflow flaw was found in the way the Linux kernel's virtio-net subsystem handled certain fraglists when the GRO (Generic Receive Offload) functionality was enabled in a bridged network configuration. An attacker on the local network could potentially use this flaw to crash the system, or, although unlikely, elevate their privileges on the system. (CVE-2015-5156, Moderate) * It was found that the Linux kernel's IPv6 network stack did not properly validate the value of the MTU variable when it was set. A remote attacker could potentially use this flaw to disrupt a target system's networking (packet loss) by setting an invalid MTU value, for example, via a NetworkManager daemon that is processing router advertisement packets running on the target system. (CVE-2015-8215, Moderate) * A NULL pointer dereference flaw was found in the way the Linux kernel's network subsystem handled socket creation with an invalid protocol identifier. A local user could use this flaw to crash the system. (CVE-2015-8543, Moderate) * It was found that the espfix functionality does not work for 32-bit KVM paravirtualized guests. A local, unprivileged guest user could potentially use this flaw to leak kernel stack addresses. (CVE-2014-8134, Low) * A flaw was found in the way the Linux kernel's ext4 file system driver handled non-journal file systems with an orphan list. An attacker with physical access to the system could use this flaw to crash the system or, although unlikely, escalate their privileges on the system. (CVE-2015-7509, Low) * A NULL pointer dereference flaw was found in the way the Linux kernel's ext4 file system driver handled certain corrupted file system images. An attacker with physical access to the system could use this flaw to crash the system. (CVE-2015-8324, Low) Red Hat would like to thank Nadav Amit for reporting CVE-2010-5313 and CVE-2014-7842, Andy Lutomirski for reporting CVE-2014-8134, and Dmitriy Monakhov (OpenVZ) for reporting CVE-2015-8324. The CVE-2015-5156 issue was discovered by Jason Wang (Red Hat).
