Threats affecting pkg:cargo/github/sfackler/rust-openssl

CVE-2025-3416 is a use-after-free vulnerability in the rust-openssl library affecting version 0.10.39. The flaw arises from improper handling of the properties argument in certain functions, potentially causing undefined behavior or incorrect property parsing. This may lead OpenSSL to treat input as an empty string. The vulnerability has a low CVSS score of 3.7, reflecting low impact on availability and no impact on confidentiality or integrity. Currently, no official fix or mitigation meeting Red Hat's criteria is available.

A timing-based side-channel flaw exists in the rust-openssl package, which could be sufficient to recover a plaintext across a network in a Bleichenbacher-style attack. To achieve successful decryption, an attacker would have to be able to send a large number of trial messages for decryption. The vulnerability affects the legacy PKCS#1v1.5 RSA encryption padding mode.
