Summary
A vulnerability has been identified in the libarchive library, triggered when file streams are piped into bsdtar, causing an out-of-bounds read. This can lead to unpredictable program behavior, memory corruption, or denial of service.
Risk Assessment
The risk for the organization includes potential disruption of services using libarchive, leading to system unavailability or data loss due to memory corruption.
Recommendation
It is recommended to immediately update the libarchive library to the latest patched version and avoid processing untrusted file streams with bsdtar until the patch is applied.

- CVE-2016-8689High
The read_Header function in archive_read_support_format_7zip.c in libarchive 3.2.1 allows remote attackers to cause a denial of service (out-of-bounds read) via multiple EmptyStream attributes in a header in a 7zip archive.
- CVE-2016-8687High
A stack-based buffer overflow in the safe_fprintf function in tar/util.c in libarchive 3.2.1 allows remote attackers to cause a denial of service via a crafted non-printable multibyte character in a filename.
- CVE-2017-5601High
An error in the lha_read_file_header_1() function in libarchive 3.2.2 allows remote attackers to trigger an out-of-bounds read memory access, potentially causing a crash via a specially crafted archive.
- CVE-2016-4736High
libarchive in Apple OS X before 10.12 allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via a crafted file.
- CVE-2016-6250High
Integer overflow in the ISO9660 writer in libarchive before 3.2.1 allows remote attackers to cause a denial of service (application crash) or execute arbitrary code via vectors related to verifying filename lengths when writing an ISO9660 archive, which trigger a buffer overflow.
Original NVD description (English source)
A vulnerability has been identified in the libarchive library. This flaw can be triggered when file streams are piped into bsdtar, potentially allowing for reading past the end of the file. This out-of-bounds read can lead to unintended consequences, including unpredictable program behavior, memory corruption, or a denial-of-service condition.
