Descriptions

huft_build in archival/libarchive/decompress_gunzip.c in BusyBox before 1.27.2 misuses a pointer, causing segfaults and an application crash during an unzip operation on a specially crafted ZIP file.

huft_build en archival/libarchive/decompress_gunzip.c en BusyBox en versiones anteriores a la 1.27.2 utiliza incorrectamente un puntero, provocando segfaults y un cierre inesperado de la aplicaciĆ³n durante una operaciĆ³n unzip en un archivo ZIP especialmente manipulado.

Tyler Hicks discovered that BusyBox incorrectly handled symlinks inside tar archives. If a user or automated system were tricked into processing a specially crafted tar archive, a remote attacker could overwrite arbitrary files outside of the current directory. This issue only affected Ubuntu 14.04 LTS and Ubuntu 16.04 LTS. Mathias Krause discovered that BusyBox incorrectly handled kernel module loading restrictions. A local attacker could possibly use this issue to bypass intended restrictions. This issue only affected Ubuntu 14.04 LTS. Various other issues were also addressed.
