An issue was discovered in py-lmdb 0.97. There is a divide-by-zero error in the function mdbenvopen2 if mdbenvreadheader obtains a zero value for a certain size field. NOTE: this outcome occurs when accessing a data.mdb file supplied by an attacker...

Debian DLA-1823-1 : linux security update (SACK Panic) (SACK Slowness)

Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks. CVE-2019-3846, CVE-2019-10126 huangwen reported multiple buffer overflows in the Marvell wifi mwifiex driver, which a local user could use to cause...

Denial Of Service (DoS)

Linux kernel is vulnerable to denial of service attacks. A race condition between direct and memory-mapped I/O which is handled with BUGON instead of an I/O failure enables local users to cause a denial of service via system crash. Affected is the functionality of file fs/xfs/xfsaops.c of the...

kernel: fuse-backed file mmap-ed onto process cmdline arguments causes denial of service

By mmaping a FUSE-backed file onto a process's memory containing command line arguments or environment strings, an attacker can cause utilities from psutils or procps such as ps, w or any other program which makes a read call to the /proc//cmdline or /proc//environ files to block indefinitely...

Linux kernel denial of service vulnerability (CNVD-2017-37597)

The Linux kernel is a computer operating system kernel written in C and assembly language, compliant with the POSIX standard, and distributed under the GNU General Public License. A denial of service vulnerability exists in the KVM in Linux kernel. An attacker can exploit this vulnerability to...

The vulnerability of the `megasas_mmio_write` function in the QEMU hardware emulation software allows a hacker to exert unpredictable effects.

The vulnerability of the megasasmmiowrite function in the QEMU hardware emulation software is caused by buffer overflow. Exploiting this vulnerability allows a remote attacker to exert unpredictable effects using unknown vectors...

kernel: race condition between direct and memory-mapped I/O in fs/xfs/xfs_aops.c

It was found that the Linux kernel can hit a BUGON statement in the xfsgetblocks in the fs/xfs/xfsaops.c because of a race condition between direct and memory-mapped I/O associated with a hole in a file that is handled with BUGON instead of an I/O failure. This allows a local unprivileged attacke...

DEBIAN-CVE-2017-7995

Xen PV guest before Xen 4.3 checked access permissions to MMIO ranges only after accessing them, allowing host PCI device space memory reads, leading to information disclosure. This is an error in the getuser function. NOTE: the upstream Xen Project considers versions before 4.5.x to be EOL...

ARM guests may induce host asynchronous abort

ISSUE DESCRIPTION Depending on how the hardware and firmware have been integrated, guest-triggered asynchronous aborts SError on ARMv8 may be received by the hypervisor. The current action is to crash the host. A guest might trigger an asynchronous abort when accessing memory mapped hardware in a...
