Experts Uncover New 'CosmicStrand' UEFI Firmware Rootkit Used by Chinese Hackers

An unknown Chinese-speaking threat actor has been attributed to a new kind of sophisticated Unified Extensible Firmware Interface UEFI firmware rootkit called CosmicStrand. "The rootkit is located in the firmware images of Gigabyte or ASUS motherboards, and we noticed that all these images are...

CosmicStrand: the discovery of a sophisticated UEFI firmware rootkit

Introduction Rootkits are malware implants which burrow themselves in the deepest corners of the operating system. Although on paper they may seem attractive to attackers, creating them poses significant technical challenges and the slightest programming error has the potential to completely cras...

Debian DLA-3012-1 : libxml2 - LTS security update

The remote Debian 9 host has packages installed that are affected by a vulnerability as referenced in the dla-3012 advisory. Felix Wilhelm discovered that libxml2, the GNOME XML library, did not correctly check for integer overflows or used wrong types for buffer sizes. This could result in...

Denial Of Service (DoS)

libxml2.so is vulnerable to denial of service. The xmlBufCreateSize function of buf.c does not properly check types of buffer sizes, allowing an attacker to crash the application by providing large multi-gigabyte buffers...

CVE-2022-29824

In libxml2 before 2.9.14, several buffer handling functions in buf.c xmlBuf and tree.c xmlBuffer don't check for integer overflows. This can result in out-of-bounds memory writes. Exploitation requires a victim to open a crafted, multi-gigabyte XML file. Other software using libxml2's buffer...

The command-line argument parser in tcpdump before 4.99.0 has a buffer overflow in tcpdump.c:read_infile(). To trigger this vulnerability the attacker needs to create a 4GB file on the local filesystem and to specify the file name as the value of the -F command-line argument of tcpdump.
