Vulnerability identifier: #VU33797

Vulnerability risk: Medium

CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2013-0211

CWE-ID: CWE-20

Exploitation vector: Network

Exploit availability: No

Vulnerable software:
libarchive
Client/Desktop applications / Software for archiving

Vendor: libarchive

Description

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

Integer signedness error in the archive_write_zip_data function in archive_write_set_format_zip.c in libarchive 3.1.2 and earlier, when running on 64-bit machines, allows context-dependent attackers to cause a denial of service (crash) via unspecified vectors, which triggers an improper conversion between unsigned and signed types, leading to a buffer overflow.

Mitigation
Install update from vendor's website.

Vulnerable software versions

libarchive: 3.1.0 - 3.1.2
