CVE-2026-97873

The Bouncy Castle for Java library (before versions 1.86 and LTS 2.73.13 ) contains a vulnerability where the raw JCA provider's legacy PBES1 and PKCS#12 PBE families derive keys using an iteration count from untrusted input without bounding. An attacker could provide a small input to dictate an ...

CVE-2026-97873 Legacy PBES1 and PKCS#12 PBE iteration count honoured unbounded in the raw JCA provider

In Bouncy Castle for Java before 1.86, the raw JCA provider's legacy PBES1 PKCS5 scheme 1 and PKCS12 PBE families ran their password-based key derivation with an iteration count taken from untrusted input without bounding it, so a small input could dictate an arbitrary amount of work before...
