A vulnerability was found in libarchive up to 3.2.0 (File Compression Software). It has been classified as critical. This affects the function read_SubStreamsInfo of the file archive_read_support_format_7zip.c of the component 7zip File Handler. The manipulation with an unknown input leads to a integer overflow vulnerability. CWE is classifying the issue as CWE-190. The product performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Integer overflow in the read_SubStreamsInfo function in archive_read_support_format_7zip.c in libarchive before 3.2.1 allows remote attackers to execute arbitrary code via a 7zip file with a large number of substreams, which triggers a heap-based buffer overflow.

The weakness was published 09/21/2016 by Cisco with Cisco Talos (Website). It is possible to read the advisory at blog.talosintel.com. This vulnerability is uniquely identified as CVE-2016-4300 since 04/27/2016. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation.
