CVE-2016-1541

Desbordamiento de buffer basado en memoria dinámica en la función zip_read_mac_metadata en archive_read_support_format_zip.c en libarchive en versiones anteriores a 3.2.0 permite a atacantes remotos ejecutar código arbitrario a través de valores entry-size manipulados en un archivo ZIP.

A vulnerability was found in libarchive. A specially crafted zip file can provide an incorrect compressed size, which may allow an attacker to place arbitrary code on the heap and execute it in the context of the application.

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.
