Amazon Linux 2023 : openssl, openssl-devel, openssl-fips-provider-latest (ALAS2023-2026-1434)
high Nessus Plugin ID 299523
Synopsis
The remote Amazon Linux 2023 host is missing a security update.Description
It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1434 advisory.If an application using the SSL_CIPHER_find() function in a QUIC protocol client or server receives an unknown cipher suite from the peer, a NULL dereference occurs. (CVE-2025-15468)
A TLS 1.3 connection using certificate compression can be forced to allocate a large buffer before decompression without checking against the configured certificate size limit. (CVE-2025-66199)
Writing large, newline-free data into a BIO chain using the line-buffering filter where the next BIO performs short writes can trigger a heap-based out-of-bounds write. (CVE-2025-68160)
When using the low-level OCB API directly with AES-NI or other hardware-accelerated code paths, inputs whose length is not a multiple of 16 bytes can leave the final partial block unencrypted and unauthenticated. (CVE-2025-69418)
Calling PKCS12_get_friendlyname() function on a maliciously crafted PKCS#12 file with a BMPString (UTF-16BE) friendly name containing non-ASCII BMP code point can trigger a one byte write before the allocated buffer. (CVE-2025-69419)
A type confusion vulnerability exists in the TimeStamp Response verification code where an ASN1_TYPE union member is accessed without first validating the type, causing an invalid or NULL pointer dereference when processing a malformed TimeStamp Response file. (CVE-2025-69420)
Processing a malformed PKCS#12 file can trigger a NULL pointer dereference in the PKCS12_item_decrypt_d2i_ex() function. (CVE-2025-69421)
An invalid or NULL pointer dereference can happen in an application processing a malformed PKCS#12 file.
(CVE-2026-22795)
ASN1_TYPE Type Confusion in the PKCS7_digest_from_attributes() function
NOTE: https://openssl-library.org/news/secadv/20260127.txt (CVE-2026-22796)
Tenable has extracted the preceding description block directly from the tested product security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
Solution
Run 'dnf update openssl --releasever 2023.10.20260216' or or 'dnf update --advisory ALAS2023-2026-1434 --releasever 2023.10.20260216' to update your system.See Also
