Descriptions
The read_CodersInfo function in archive_read_support_format_7zip.c in libarchive before 3.2.0 allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via a crafted 7z file, related to the _7z_folder struct.
La función read_CodersInfo en archive_read_support_format_7zip.c en libarchive en versiones anteriores a 3.2.0 permite a atacantes remotos provocar una denegación de servicio (referencia a puntero NULL y caída) a través de un archivo 7z manipulado, relacionado con la estructura the _7z_folder.
A vulnerability was found in libarchive. A specially crafted 7Z file could trigger a NULL pointer dereference, causing the application to crash.
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.
