Descriptions
The archive_read_format_cpio_read_header function in archive_read_support_format_cpio.c in libarchive before 3.2.1 allows remote attackers to cause a denial of service (application crash) via a CPIO archive with a large symlink.
La función archive_read_format_cpio_read_header en archive_read_support_format_cpio.c en libarchive en versiones anteriores a 3.2.1 permite a atacantes remotos provocar denegación de servicio (caída de aplicación) a través de un archivo CPIO con un enlace simbólico grande.
A vulnerability was found in libarchive. A specially crafted cpio archive containing a symbolic link to a ridiculously large target path can cause memory allocation to fail, resulting in any attempt to view or extract the archive crashing.
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.
