    Package        : osslsigncode
    Version        : 2.5-4~deb11u1
    CVE ID         : CVE-2023-36377
    Debian Bug     : 1035875

    A Buffer Overflow vulnerability has been found in osslsigncode, a
    OpenSSL based Authenticode signing tool for PE/MSI/Java CAB files,
    which possibly allows an malicious attacker to execute arbitrary code
    when signing a crafted file.

    For Debian 11 bullseye, this problem has been fixed in version
    2.5-4~deb11u1.

    We recommend that you upgrade your osslsigncode packages.

    For the detailed security status of osslsigncode please refer to
    its security tracker page at:
    https://security-tracker.debian.org/tracker/osslsigncode
