Description
The libarchive programming library can create and read several different
streaming archive formats, including GNU tar and cpio. It can also read ISO
9660 CD-ROM images.
Two heap-based buffer overflow flaws were discovered in libarchive. If a
user were tricked into expanding a specially-crafted ISO 9660 CD-ROM image
or tar archive with an application using libarchive, it could cause the
application to crash or, potentially, execute arbitrary code with the
privileges of the user running the application. (CVE-2011-1777,
CVE-2011-1778)
