Synopsis

The remote Debian host is missing a security update.

Description

Fuzzing found two further file-format specific issues in libarchive, a read-only segfault in 7z, and an infinite loop in ISO9660.

CVE-2019-1000019

Out-of-bounds Read vulnerability in 7zip decompression, that can result in a crash (denial of service, CWE-125) CVE-2019-1000020
