Security Bulletin

This security bulletin contains information about 6 vulnerabilities.

1) Memory corruption

EUVDB-ID: #VU13574

Risk: Low

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2018-10958

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to boundary error in types.cpp when processing a large size value. A remote attacker can perform Exiv2::Internal::PngChunk::zlibUncompress call and cause a SIGABRT during an attempt at memory allocation.

Mitigation

Update the affected package to version: 0.25-3.1+deb9u1

Vulnerable software versions

Debian Linux: All versions
