    Package        : jackson-core
    CVE ID         : CVE-2025-52999
    Debian Bug     : 1108367

    A flaw was discovered in jackson-core, a fast and powerful JSON library for
    Java, which may allow an attacker to cause a denial of service by using deeply
    nested JSON data.

    Please note that related and complementary jackson-* packages like jackson-
    databind or jackson-dataformat-smile had to be upgraded as well in
    order to fix build failures caused by the changes to jackson-core.

    For the oldstable distribution (bookworm), this problem has been fixed
    in version 2.14.1-2~deb12u1.

    For the stable distribution (trixie), this problem has been fixed in
    version 2.14.1-2~deb13u1.

    We recommend that you upgrade your jackson-core packages.

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