Description

This security bulletin contains information about 1 vulnerability.


1) Use-after-free (CVE-ID: CVE-2026-28387)

CWE-ID: CWE-416 - Use After Free

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


The vulnerability allows a remote attacker to execute arbitrary code.

The vulnerability exists due to use-after-free in DANE client code when processing server DANE TLSA records during TLSA-based server authentication. A remote attacker can provide crafted TLSA records to execute arbitrary code.

The issue only affects clients that use both PKIX-TA(0) or PKIX-EE(1) certificate usages together with the DANE-TA(2) certificate usage, and the server must publish a TLSA RRset containing both record types.
