CVE-2021-21827

CVE-2021-21827 is a heap-based buffer overflow vulnerability in AT&T Labs Xmill 0.7, triggered by DecodeTreeBlock during XMI decompression. The vulnerability arises when a UINT32 read from the input is used as the length for a buffer during various decode paths, leading to unsafe copies via memcp...

CVE-2021-21826

A heap-based buffer overflow vulnerability exists in the XML Decompression DecodeTreeBlock functionality of AT&T Labs Xmill 0.7. Within DecodeTreeBlock which is called during the decompression of an XMI file, a UINT32 is loaded from the file and used as trusted input as the length of a buffer. An...

CVE-2021-21826

CVE-2021-21826 is a heap-based buffer overflow in AT&T Labs Xmill 0.7, within XML Decompression DecodeTreeBlock. A crafted XMI file triggers a UINT32-derived length for an internal buffer, enabling a attacker-controlled input to overflow. The initial description confirms the vulnerability, includ...

How to proactively defend against Mozi IoT botnet

Mozi is a peer-to-peer P2P botnet that uses a BitTorrent-like network to infect IoT devices such as network gateways and digital video records DVRs. It works by exploiting weak telnet passwords1 and nearly a dozen unpatched IoT vulnerabilities2 and it’s been used to conduct distributed...
