critical Nessus Plugin ID 344680

Synopsis

The remote SUSE host is missing one or more security updates.

Description

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:3835-1 advisory.

OpenSSL is updated to 3.5.0 in SLE-15-SP7: (jsc#PED-16072)

- Move ssl configuration files to the libopenssl package [bsc#1247463]
- Don't install unneeded NOTES
- Disable LTO for userspace livepatching [jsc#PED-13245]
- Fix P-384 curve on lower-than-P9 PPC64 targets [bsc#1243014]
- FIPS: Fix the speed command in FIPS mode for KMAC

- FIPS: Restore the check to deny SHA1 signatures in FIPS mode and the functionality to allow/deny via crypto-policies. [jsc#PED-12224]

Update to 3.5.0:

* Changes:

- Default encryption cipher for the req, cms, and smime applications changed from des-ede3-cbc to aes-256-cbc.
- The default TLS supported groups list has been changed to include and prefer hybrid PQC KEM groups. Some practically unused groups were removed from the default list.
- The default TLS keyshares have been changed to offer X25519MLKEM768 and and X25519.
- All BIO_meth_get_*() functions were deprecated.

* New features:

- Support for server side QUIC (RFC 9000)
- Support for 3rd party QUIC stacks including 0-RTT support
- Support for PQC algorithms (ML-KEM, ML-DSA and SLH-DSA)
- A new configuration option no-tls-deprecated-ec to disable support for TLS groups deprecated in RFC8422
- A new configuration option enable-fips-jitter to make the FIPS provider to use the JITTER seed source
- Support for central key generation in CMP
- Support added for opaque symmetric key objects (EVP_SKEY)
- Support for multiple TLS keyshares and improved TLS key establishment group configurability
- API support for pipelining in provided cipher algorithms

Changes between 3.3.0 and 3.4.0:

* Changes:

- Deprecation of TS_VERIFY_CTX_set_* functions and addition of replacement TS_VERIFY_CTX_set0_* functions with improved semantics
- The X25519 and X448 key exchange implementation in the FIPS provider is unapproved and has fips=no property.
- SHAKE-128 and SHAKE-256 implementations have no default digest length anymore. That means these algorithms cannot be used with EVP_DigestFinal/_ex() unless the xoflen param is set before.
- Setting config_diagnostics=1 in the config file will cause errors to be returned from SSL_CTX_new() and SSL_CTX_new_ex() if there is an error in the ssl module configuration.
- An empty renegotiate extension will be used in TLS client hellos instead of the empty renegotiation SCSV, for all connections with a minimum TLS version > 1.0.
- Deprecation of SSL_SESSION_get_time(), SSL_SESSION_set_time() and SSL_CTX_flush_sessions() functions in favor of their respective _ex functions which are Y2038-safe on platforms with Y2038-safe time_t

* New features:

- Support for directly fetched composite signature algorithms such as RSA-SHA2-256 including new API functions
- FIPS indicators support in the FIPS provider and various updates of the FIPS provider required for future FIPS 140-3 validations
- Implementation of RFC 9579 (PBMAC1) in PKCS#12
- An optional additional random seed source RNG JITTER using a statically linked jitterentropy library
- New options -not_before and -not_after for explicit setting start and end dates of certificates created with the req and x509 apps
- Support for integrity-only cipher suites TLS_SHA256_SHA256 and TLS_SHA384_SHA384 in TLS 1.3, as defined in RFC 9150
- Support for retrieving certificate request templates and CRLs in CMP
- Support for additional X.509v3 extensions related to Attribute Certificates
- Initial Attribute Certificate (RFC 5755) support
- Possibility to customize ECC groups initialization to use precomputed values to save CPU time and use of this feature by the P-256 implementation

Changes between 3.2.0 and 3.3.0:

* Changes:

- Optimized AES-CTR for ARM Neoverse V1 and V2
- Various optimizations for cryptographic routines using RISC-V vector crypto extensions
- Added assembly implementation for md5 on loongarch64
- Accept longer context for TLS 1.2 exporters
- The activate and soft_load configuration settings for providers in openssl.cnf have been updated to require a value of [1|yes|true|on] (in lower or UPPER case) to enable the setting. Conversely a value of [0|no|false|off] will disable the setting.
- In openssl speed, changed the default hash function used with hmac from md5 to sha256.
- The -verify option to the openssl crl and openssl req will make the program exit with 1 on failure.
- The d2i_ASN1_GENERALIZEDTIME(), d2i_ASN1_UTCTIME(), ASN1_TIME_check(), and related functions have been augmented to check for a minimum length of the input string, in accordance with ITU-T X.690 section 11.7 and 11.8.
- OPENSSL_sk_push() and sk__push() functions now return 0 instead of -1 if called with a NULL stack argument.
- New limit on HTTP response headers is introduced to HTTP client.
The default limit is set to 256 header lines.

* Bug fixes and mitigations:

- The BIO_get_new_index() function can only be called 127 times before it reaches its upper bound of BIO_TYPE_MASK and will now return -1 once its exhausted.

* new features:

- Support for qlog for tracing QUIC connections has been added
- Added APIs to allow configuring the negotiated idle timeout for QUIC connections, and to allow determining the number of additional streams that can currently be created for a QUIC connection.
- Added APIs to allow disabling implicit QUIC event processing for QUIC SSL objects
- Added APIs to allow querying the size and utilisation of a QUIC stream's write buffer
- New API SSL_write_ex2, which can be used to send an end-of-stream (FIN) condition in an optimised way when using QUIC.
- Limited support for polling of QUIC connection and stream objects in a non-blocking manner.
- Added a new EVP_DigestSqueeze() API. This allows SHAKE to squeeze multiple times with different output sizes.
- The BLAKE2s hash algorithm matches BLAKE2b's support for configurable output length.
- The EVP_PKEY_fromdata function has been augmented to allow for the derivation of CRT (Chinese Remainder Theorem) parameters when requested
- Added API functions SSL_SESSION_get_time_ex(), SSL_SESSION_set_time_ex() using time_t which is Y2038 safe on 32 bit systems when 64 bit time is enabled.
- Unknown entries in TLS SignatureAlgorithms, ClientSignatureAlgorithms config options and the respective calls to SSL[_CTX]_set1_sigalgs() and SSL[_CTX]_set1_client_sigalgs() that start with ? character are ignored and the configuration will still be used.
- Added -set_issuer and -set_subject options to openssl x509 to override the Issuer and Subject when creating a certificate. The -subj option now is an alias for -set_subject.
- Added several new features of CMPv3 defined in RFC 9480 and RFC 9483
- New option SSL_OP_PREFER_NO_DHE_KEX, which allows configuring a TLS1.3 server to prefer session resumption using PSK-only key exchange over PSK with DHE, if both are available.
- New atexit configuration switch, which controls whether the OPENSSL_cleanup is registered when libcrypto is unloaded.
- Added X509_STORE_get1_objects to avoid issues with the existing X509_STORE_get0_objects API in multi-threaded applications.
- Support for using certificate profiles and extened delayed delivery in CMP

- FIPS: Mark SHA-1 as non-approved in the SLI. [jsc#PED-12224]

- Introduce --without lto. When %{optflags} contains -flto=*, tests cases are also built using -flto=* which significantly increases build times, this option disables lto which improve iteration times when developing.

Update to 3.2.4:

- Remove the engines' directories and symlinks that were added to allow parallel installations with openssl-1_1.
- Add ktls capability [bsc#1216950]

This update also rebuilds nodejs24 to enable PQC.

Tenable has extracted the preceding description block directly from the SUSE 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

Update the affected packages.
