libarchive -- multiple vulnerabilities
Integer signedness error in the archive_write_zip_data function in
archive_write_set_format_zip.c in libarchive 3.1.2 and earlier, when
running on 64-bit machines, allows context-dependent attackers to
cause a denial of service (crash) via unspecified vectors, which
triggers an improper conversion between unsigned and signed types,
leading to a buffer overflow.
Absolute path traversal vulnerability in bsdcpio in libarchive
3.1.2 and earlier allows remote attackers to write to arbitrary
files via a full pathname in an archive.
Libarchive issue tracker reports:
Using a crafted tar file bsdtar can perform an out-of-bounds memory
read which will lead to a SEGFAULT. The issue exists when the
executable skips data in the archive. The amount of data to skip is
defined in byte offset [16-19] If ASLR is disabled, the issue can
lead to an infinite loop.
