Description

This security bulletin contains information about 1 vulnerability.


1) Out-of-bounds read (CVE-ID: CVE-2026-40253)

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

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to disclose sensitive information and cause a denial of service.

The vulnerability exists due to out-of-bounds read in BER/DER decoding functions in usr/lib/common/asn1.c when parsing malformed BER-encoded cryptographic objects with attacker-controlled length fields. A remote attacker can supply a specially crafted key or certificate to disclose sensitive information and cause a denial of service.

The issue affects the shared common library and impacts all token backends, including Soft, ICA, CCA, TPM, EP11, and ICSF.
