Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from idpf not properly setting up the calculation of checksums before transferring headers, which could result in...

DEBIAN-CVE-2024-3567

A flaw was found in QEMU. An assertion failure was present in the updatesctpchecksum function in hw/net/nettxpkt.c when trying to calculate the checksum of a short-sized fragmented packet. This flaw allows a malicious guest to crash QEMU and cause a denial of service condition...

CVE-2020-17441

CVE-2020-17441 affects picoTCP 1.7.0, specifically the IPv6 processing code in pico_ipv6_extension_headers and pico_checksum_adder (pico_ipv6.c, pico_frame.c). The issue arises from not validating the IPv6 payload length against the actual payload when computing the ICMPv6 checksum, causing an ou...

CVE-2020-13987

An issue was discovered in Contiki through 3.0. An Out-of-Bounds Read vulnerability exists in the uIP TCP/IP Stack component when calculating the checksums for IP packets in upperlayerchksum in net/ipv4/uip.c...

Remote Code Execution (RCE)

udp.c in the Linux kernel is vulnerable Remote Code Execution RCE. It allows remote attackers to execute arbitrary code via UDP traffic that triggers an unsafe second checksum calculation during execution of a recv system call with the MSGPEEK flag...

CVE-2019-3701

An issue was discovered in cancangwrcv in net/can/gw.c in the Linux kernel through 4.19.13. The CAN frame modification rules allow bitwise logical operations that can be also applied to the candlc field. The privileged user "root" with CAPNETADMIN can create a CAN frame modification rule that mak...

New upstream release - This fixes the security bug known as CVE-2018-5345 - Add new API for fwupd - Do not encode timezone in generated files - Fix countless memory leaks when parsing corrupt files - Fix the calculation of the checksum on big endian machines - Switch to the Meson buildsystem Note...

How to solve the Malwarebytes CrackMe: a step-by-step tutorial

The topic of this post is a Malwarebytes CrackMe—an exercise in malware analysis that I recently created. First, the challenge was created to serve internal purposes, but then it was released to the community on Twitter and triggered a lot of positive response. Thanks to all of you who sent in yo...

Important: kernel

Issue Overview: Unsafe second checksum calculation in udp.c: The Linux kernel allows remote attackers to execute arbitrary code via UDP traffic that triggers an unsafe second checksum calculation during execution of a recv system call with the MSGPEEK flag. This may create a kernel panic or memor...

EGESPLOIT - A Golang Library For Malware Development

EGESPLOIT is a golang library for malware development, it has few unique functions for meterpreter integration. DOCUMENTATION CalculateChecksumx : Function calculates x digit 8 bit checksum for reverse HTTP/HTTPS meterpreter connections, returns the calculated checksum as string...

Qemu: net: out of bounds read in net_checksum_calculate()

An out-of-bounds read-access flaw was found in the QEMU emulator built with IP checksum routines. The flaw could occur when computing a TCP/UDP packet's checksum, because a QEMU function used the packet's payload length without checking against the data buffer's size. A user inside a guest could...
