The remote FreeBSD host is missing a security-related update.


MITRE reports :

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.


Update the affected package.
