Risk: Medium

CVSSv4.0: 1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2019-19221

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition in "archive_wstring_append_from_mbs" in "archive_string.c" because of an incorrect "mbrtowc" or "mbtowc" call. A remote attacker can create a specially crafted archive file, trick the victim into opening it, trigger out-of-bounds read error and read contents of memory on the system.

Mitigation

Update the affected package libarchive to the latest version.
