Descriptions
The _ar_read_header function in archive_read_support_format_ar.c in libarchive before 3.2.0 allows remote attackers to cause a denial of service (out-of-bounds stack read) via a crafted ar file.
La función lha_ar_read_header en archive_read_support_format_ar.c en libarchive en versiones anteriores a 3.2.0 permite a atacantes remotos provocar una denegación de servicio (lectura de pila fuera de rango) a través de un archivo ar manipulado.
A vulnerability was found in libarchive. A specially crafted AR archive could cause the application to read a single byte of application memory, potentially disclosing it to the attacker.
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.
