critical Nessus Plugin ID 327307

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 a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:3026-1 advisory.

 This update for python-cryptography fixes the following issues

 - CVE-2026-41676: openssl: `Deriver:derive` and `PkeyCtxRef:derive` can overflow short buffers on OpenSSL 1.1.1 (bsc#1270208).
 - CVE-2026-41677: openssl: out-of-bounds read in PEM password callback when returning an oversized length in rust- openssl crate (bsc#1270620).
 - CVE-2026-41678: openssl: incorrect bounds assertion in aes key wrap in rust-openssl crate (bsc#1270706).
 - CVE-2026-41681: openssl: MdCtxRef::digest_final() writes past caller buffer with no length check in rust-openssl crate (bsc#1270772).
 - CVE-2026-41898: openssl: unchecked callback-returned length in PSK and cookie generate trampolines can leak adjacent memory in rust-openssl crate (bsc#1270801).
 - CVE-2026-42327: openssl: arbitrary code execution via specially crafted certificate in rust-openssl crate (bsc#1270515).
 - CVE-2026-44662: openssl: heap buffer overflow when encrypting with AES key-wrap-with-padding in rust- openssl crate (bsc#1270936).
 - CVE-2026-45784: openssl: out-of-bounds write in `CipherCtxRef::cipher_update_inplace` for AES-KW-PAD ciphers in rust- openssl crate (bsc#1270994).

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 python311-cryptography package.
