NVD Description

Note: Versions mentioned in the description apply only to the upstream libarchive package and not the libarchive package as distributed by Oracle. See How to fix? for Oracle:8 relevant fixed versions and status.

libarchive version commit bf9aec176c6748f0ee7a678c5f9f9555b9a757c1 onwards (release v3.0.2 onwards) contains a CWE-125: Out-of-bounds Read vulnerability in 7zip decompression, archive_read_support_format_7zip.c, header_bytes() that can result in a crash (denial of service). This attack appears to be exploitable via the victim opening a specially crafted 7zip file.
