Amazon Linux 2023 : ngtcp2, ngtcp2-crypto-gnutls, ngtcp2-crypto-gnutls-devel (ALAS2023-2026-1633)

It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2026-1633 advisory. ngtcp2 is a C implementation of the IETF QUIC protocol. In versions prior to 1.22.1, ngtcp2qlogparameterssettransportparams serializes peer transport parameters into a fixed 1024-byte stack buffer...

SUSE CVE-2024-52811

The ngtcp2 project is an effort to implement IETF QUIC protocol in C. In affected versions acks are not validated before being written to the qlog leading to a buffer overflow. In ngtcp2conn::connrecvpkt for an ACK, there was new logic that got added to skip connrecvack if an ack has already been...
