CVE-2024-3094

CVE-2024-3094 Se descubrió código malicioso en los tarballs ascendentes de xz, a partir de la versión 5.6.0. Mediante una serie de complejas ofuscaciones, el proceso de compilación de liblzma extrae un archivo objeto precompilado de un archivo de prueba disfrazado que existe en el código fuente, ...

CVE-2024-3094

CVE-2024-3094 Se descubrió código malicioso en los tarballs oficiales de xz, a partir de la versión 5.6.0. Mediante una serie de complejas ofuscaciones, el proceso de compilación de liblzma extrae un archivo objeto precompilado de un archivo de prueba disfrazado presente en el código fuente, que...

JLSEC-2026-62

Malicious code was discovered in the upstream tarballs of xz, starting with version 5.6.0. Through a series of complex obfuscations, the liblzma build process extracts a prebuilt object file from a disguised test file existing in the source code, which is then used to modify specific functions in...

Injected Malicious Code

XZ is vulnerable to Injected Malicious Code. Malicious code was discovered in the upstream tarballs of xz, starting with version 5.6.0. Through a series of complex obfuscations, the liblzma build process extracts a prebuilt object file from a disguised test file existing in the source code, which...

golang: malicious symbol names can lead to code execution at build time

An input validation vulnerability was found in Go. From a generated go file from the cgo tool, it is possible to modify symbols within that object file and specify code. This flaw allows an attacker to create a repository that includes malicious pre-built object files that could execute arbitrary...
