CVE-2021-26951

An issue was discovered in the calamine crate before 0.17.0 for Rust. It allows attackers to overwrite heap-memory locations because Vec::setlen is used without proper memory claiming, and this uninitialized memory is used for a user-provided Read operation, as demonstrated by Sectors::get...

libmysofa Heap Buffer Overflow Vulnerability

libmysofa is a lightweight C library for reading AES SOFA files. A heap buffer overflow vulnerability exists in libmysofa 0.5 - 1.1. The vulnerability stems from the mysofaresamplerresetmem function failing to handle input data correctly. An attacker can exploit this vulnerability to cause a heap...

Sudo Heap-Based Buffer Overflow

A heap based buffer overflow exists in the sudo command line utility that can be exploited by a local attacker to gain elevated privileges. The vulnerability was introduced in July of 2011 and affects version 1.8.2 through 1.8.31p2 as well as 1.9.0 through 1.9.5p1 in their default configurations...

CVE-2020-8938

An arbitrary memory overwrite vulnerability in Asylo versions up to 0.6.0 allows an attacker to make a host call to FromkLinuxSockAddr with attacker controlled content and size of klinuxaddr which allows an attacker to write memory values from within the enclave. We recommend upgrading past commi...

CVE-2020-8937

An arbitrary memory overwrite vulnerability in Asylo versions up to 0.6.0 allows an attacker to make a host call to encuntrustedcreatewaitqueue that uses a pointer queue that relies on UntrustedLocalMemcpy, which fails to validate where the pointer is located. This allows an attacker to write...

CVE-2020-8936

An arbitrary memory overwrite vulnerability in Asylo versions up to 0.6.0 allows an attacker to make a host call to UntrustedCall. UntrustedCall failed to validate the buffer range within sgxparams and allowed the host to return a pointer that was an address within the enclave memory. This allowe...
