Title
CryptX versions before 0.088 for Perl do not reseed the Crypt::PK PRNG state after forking
Summary
CryptX versions before 0.088 for Perl do not reseed the Crypt::PK PRNG state after forking.
The Crypt::PK::RSA, Crypt::PK::DSA, Crypt::PK::DH, Crypt::PK::ECC, Crypt::PK::Ed25519 and Crypt::PK::X25519 modules seed a per-object PRNG state in their constructors and reuse it without fork detection. A Crypt::PK::* object created before `fork()` shares byte-identical PRNG state with every child process, and any randomized operation they perform can produce identical output, including key generation. Two ECDSA or DSA signatures from different processes are enough to recover the signing private key through nonce-reuse key recovery.
This affects preforking services such as the Starman web server, where a Crypt::PK::* object loaded at startup is inherited by every worker process.

Title
Bytes::Random::Secure::Tiny versions through 1.011 for Perl share internal state across forked processes
Summary
Bytes::Random::Secure::Tiny versions through 1.011 for Perl share internal state across forked processes.
When an object is initialised before forking, then the internal state for the PRNG is shared across processes and identical random streams will be produced.
Secrets generated in multiprocess applications are predictable across processes.

Bytes::Random::Secure versions through 0.29 for Perl share internal state across forked processes.
When an object is initialised before forking, or when the functional interface is used, then the internal state for the PRNG is shared across processes and identical random streams will be produced.

Title
Fault injection attack with ML-DSA and ML-KEM on ARM
Summary
Protection mechanism failure in wolfCrypt post-quantum implementations (ML-KEM and ML-DSA) in wolfSSL on ARM Cortex-M microcontrollers allows a physical attacker to compromise key material and/or cryptographic outcomes via induced transient faults that corrupt or redirect seed/pointer values during Keccak-based expansion.
This issue affects wolfSSL (wolfCrypt): commit hash d86575c766e6e67ef93545fa69c04d6eb49400c6.

Title
Apache Cocoon: continuations may not be private
Summary
** UNSUPPORTED WHEN ASSIGNED ** Incorrect Usage of Seeds in Pseudo-Random Number Generator (PRNG) vulnerability in Apache Cocoon.
This issue affects Apache Cocoon: all versions.
When a continuation is created, it gets a random identifier. Because the random number generator used to generate these identifiers was seeded with the startup time, it may not have been sufficiently unpredictable, and an attacker could use this to guess continuation ids and look up continuations they should not have had access to.
As a mitigation, you may enable the "session-bound-continuations" option to make sure continuations are not shared across sessions.
As this project is retired, we do not plan to release a version that fixes this issue. Users are recommended to find an alternative or restrict access to the instance to trusted users.
NOTE: This vulnerability only affects products that are no longer supported by the maintainer.
