    Package        : composer
    CVE ID         : CVE-2024-35241 CVE-2024-35242

    Two vulnerabilities have been discovered in Composer, a dependency
    manager for PHP, which could result in arbitrary command execution by
    operating on malicious git/hg repositories.

    For the oldstable distribution (bullseye), these problems have been fixed
    in version 2.0.9-2+deb11u3.

    For the stable distribution (bookworm), these problems have been fixed in
    version 2.5.5-1+deb12u2.

    We recommend that you upgrade your composer packages.

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