Descriptions
The process_extra function in libarchive before 3.2.0 uses the size field and a signed number in an offset, which allows remote attackers to cause a denial of service (crash) via a crafted zip file.
La función process_extra en libarchive en versiones anteriores a 3.2.0 utiliza el campo de tamaño y un número con signo en un desplazamiento, lo que permite a atacantes remotos provocar una denegación de servicio (caída) a través de un archivo zip manipulado.
A vulnerability was found in libarchive. A specially crafted ZIP file could cause a few bytes of application memory in a 256-byte region to be disclosed.
The libarchive programming library can create and read several different streaming archive formats, including GNU tar, cpio, and ISO 9660 CD-ROM images. Libarchive is used notably in the bsdtar utility, scripting language bindings such as python-libarchive, and several popular desktop file managers. Security Fix: A flaw was found in the way libarchive handled hardlink archive entries of non-zero size. Combined with flaws in libarchive's file system sandboxing, this issue could cause an application using libarchive to overwrite arbitrary files with arbitrary data from the archive.
