CVE-2025-67897
Description
A flaw was found in Sequoia. This vulnerability allows a remote attacker to crash an application via sending a victim an encrypted message with a crafted Public Key Encrypted Session Key (PKESK) or Symmetric Key Encrypted Session Key (SKESK) packet, which causes aes_key_unwrap to panic when processing a short ciphertext.
Statement
This vulnerability is rated Moderate for Red Hat. A remote attacker could crash an application using Sequoia by sending a specially crafted encrypted message. Successful exploitation requires high attack complexity and user interaction, as the victim must process the malicious message.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
