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.
