CVE-2026-13586
|
| Summary | PKCS#12 MAC and bag-decryption KDF iteration-count bound (DoS) Affects Bouncy Castle for Java before 1.85. PKCS12KeyStoreSpi and PKCS12PBMAC1KeyStoreSpi derived integrity-MAC and bag-decryption keys using iteration counts taken from the keystore file with no ceiling. A file of a few hundred bytes declaring a count near 2^31 occupies the loading thread in key derivation before any password or integrity check can fail. Counts are now validated and capped at five million by default, adjustable through org.bouncycastle.pkcs12.max_it_count. |
