on demand in crl_crldp_check() instead of\n for every DP when certificate extensions are cached\n - CVE-2026-35189\n * SECURITY UPDATE: DTLS retransmits handshake messages from a stale offset\n - debian/patches/openssl-1.1.1-cve-2026-84782.patch: reset init_off before\n resending a buffered message and skip retransmission while a handshake\n write is suspended, so a retransmit cannot read past the message buffer\n - CVE-2026-84782\n * SECURITY UPDATE: timing side-channel in EC scalar multiplication\n - debian/patches/openssl-1.1.1-cve-2026-54872.patch: pin the secret scalar to\n a fixed word width before the BN_add() padding steps in\n ec_scalar_mul_ladder(), closing a timing side-channel on the nonce\n - CVE-2026-54872\n * SECURITY UPDATE: undersized DTLS 1.2 AEAD record causes DoS\n - debian/patches/openssl-1.1.1-cve-2026-75806.patch: reject a received AEAD\n record shorter than the explicit IV plus tag before AEAD processing, so\n DTLS drops it instead of tearing the

retransmitted message can be read past the message buffer and\nthe retransmission overwrites the internal state the suspended write\nneeds to resume correctly.\n\nImpact summary: The retransmitted message can disclose a heap memory\nto the peer as plaintext handshake data or cause a crash and a Denial\nof Service when the read reaches an unmapped memory region.\n\nCWE: CWE-125: Out-of-bounds Read\n\nDescription: DTLS handshake messages can be written out in multiple\nfragments, and a write can suspend mid-message (returning WANT_WRITE)\nif the underlying transport temporarily cannot accept more data. While\nsuch a write is suspended, the DTLS retransmission timer may\nindependently fire and ask the retransmission logic to resend an\nearlier, already-acknowledged-as-sent message from its retransmit\nqueue.\n\nThe retransmission logic reused the same internal buffer and position\ntracking as the message that was still being written, without\nresetting the position back to the start of the message being\nretransmitted. As a result the retransmission was read starting from\nwherever the suspended write had left off, producing a mislabelled\nmessage whose body was leftover bytes from the other, larger message\nstill in flight - content that was never meant to be sent at that\npoint, and which could run past the end of the allocated buffer.\n\nSeparately, even when the retransmission is positioned correctly,\nallowing it to run to completion while another write is suspended\noverwrites the same shared bookkeeping that the suspended write\ndepends on to resume. When the application later resumes the\nsuspended write (via a subsequent SSL_read(), SSL_write(),\nSSL_accept(), or SSL_connect() call), it finds that bookkeeping in a\nstate inconsistent with the message and aborts the process in\na debugging build.\n\nThe fix resets the retransmission's read position to the start of the\nmessage before resending, and skips retransmission entirely whenever a\nhandshake write is still suspended, deferring to the next call that\nresumes it instead.\n\nFIPS impact: no\nThe affected code is outside the FIPS module boundary.", "title": "Vulnerability

When decrypting such a record the record layer passed the record length to\nthe cipher implementation before checking that the record was long enough to\ncontain the explicit IV and the tag. For a record shorter than that overhead the\ncipher implementation rejected the impossible length, and the record layer\ntreated this as an internal failure and raised a fatal internal_error alert\ninstead of treating the record as one that failed authentication.\n\nIn TLS 1.2 the same record causes a fatal internal_error alert instead of the\nexpected bad_record_mac alert. Since any undecryptable record already\nterminates a TLS connection, this is a protocol conformance issue rather than\na security issue in TLS.\n\nThe fix validates the record length against the
