    For general information regarding FreeBSD Security Advisories,
    including descriptions of the fields above, security branches, and the following sections, please visit <URL:https://security.FreeBSD.org/>.

    I. Background

    FreeBSD includes software from the OpenSSL Project. The OpenSSL Project is a collaborative effort to develop a robust, commercial-grade, full-featured
    Open Source toolkit for the Transport Layer Security (TLS) protocol. It is also a general-purpose cryptography library.

    II. Problem Description

    Multiple issues have been reported as part of this advisory with different issues affecting different OpenSSL versions and therefore different FreeBSD versions. Instead of exhaustively listing detailed writeups for each issue, please see the referenced advisory from OpenSSL.

    Issues affecting FreeBSD 15.0 (OpenSSL 3.5):
    CVE-2025-11187 - Improper validation of PBMAC1 parameters in PKCS#12 MAC verification
    CVE-2025-15467 - Stack buffer overflow in CMS AuthEnvelopedData parsing

    CVE-2026-22795 - Missing ASN1_TYPE validation in PKCS#12 parsing
    CVE-2026-22796 - ASN1_TYPE Type Confusion in the PKCS7_digest_from_attributes() function

    Issues affecting FreeBSD 14.3 (OpenSSL 3.0):

    CVE-2026-22796 - ASN1_TYPE Type Confusion in the PKCS7_digest_from_attributes() function

    Issues affecting FreeBSD 13.5 (OpenSSL 1.1.1):
    CVE-2025-68160 - Heap out-of-bounds write in BIO_f_linebuffer on short writes
    CVE-2025-69418 - Unauthenticated/unencrypted trailing bytes with low-level OCB function calls
    CVE-2025-69419 - Out of bounds write in PKCS12_get_friendlyname() UTF-8 conversion
    CVE-2025-69420 - Missing ASN1_TYPE validation in TS_RESP_verify_response() function
    CVE-2025-69421 - NULL Pointer Dereference in PKCS12_item_decrypt_d2i_ex function

    CVE-2026-22796 - ASN1_TYPE Type Confusion in the PKCS7_digest_from_attributes() function

    III. Impact

    The issues include improper/missing validation, NULL pointer dereferences, out-of-bounds writes, incorrect data exposure, input truncation, excessive memory allocation, and a stack buffer overflow.

    Security impact can be a minimal information disclosure to a potential remote code execution. See the OpenSSL advisory for specific details.

    IV. Workaround

    No workaround is available.

    V. Solution

    Upgrade your vulnerable system to a supported FreeBSD stable or
    release / security branch (releng) dated after the correction date.

    Perform one of the following:

    1) To update your vulnerable system via a binary patch:

    Systems running a RELEASE version of FreeBSD on the amd64 or arm64 platforms, or the i386 platform on FreeBSD 13, can be updated via the freebsd-update(8) utility:

    # freebsd-update fetch
    # freebsd-update install
    # shutdown -r +10min "Rebooting for a security update"

    2) To update your vulnerable system via a source code patch:

    The following patches have been verified to apply to the applicable
    FreeBSD release branches.

    a) Download the relevant patch from the location below, and verify the
    detached PGP signature using your PGP utility.

    [FreeBSD 15.0]
    # fetch https://security.FreeBSD.org/patches/SA-26:01/openssl-15.patch
    # fetch https://security.FreeBSD.org/patches/SA-26:01/openssl-15.patch.asc
    # gpg --verify openssl-15.patch.asc

    [FreeBSD 14.3]
    # fetch https://security.FreeBSD.org/patches/SA-26:01/openssl-14.patch
    # fetch https://security.FreeBSD.org/patches/SA-26:01/openssl-14.patch.asc
    # gpg --verify openssl-14.patch.asc

    [FreeBSD 13.5]
    # fetch https://security.FreeBSD.org/patches/SA-26:01/openssl-13.patch
    # fetch https://security.FreeBSD.org/patches/SA-26:01/openssl-13.patch.asc
    # gpg --verify openssl-13.patch.asc

    b) Apply the patch. Execute the following commands as root:

    # cd /usr/src
    # patch < /path/to/patch

    c) Recompile the operating system using buildworld and installworld as described in <URL:https://www.FreeBSD.org/handbook/makeworld.html>.

    Restart all daemons that use the library, or reboot the system.

    VI. Correction details
