CVE-2025-69419

Description

A flaw was found in OpenSSL. When processing a specially crafted PKCS#12 (Personal Information Exchange Syntax Standard) file, a remote attacker can exploit an out-of-bounds write vulnerability. This issue, occurring within the OPENSSL_uni2utf8() function, leads to memory corruption by writing data beyond its allocated buffer. Successful exploitation could result in a denial of service or potentially allow for arbitrary code execution.

Statement

This vulnerability is rated Moderate for Red Hat. An out-of-bounds write in OpenSSL's PKCS12_get_friendlyname() function can lead to denial of service or arbitrary code execution. Exploitation requires an application to parse a specially crafted malicious PKCS#12 file. Red Hat FIPS modules are not affected as the PKCS#12 implementation is outside the FIPS module boundary.

Mitigation

To mitigate this vulnerability, Red Hat recommends avoiding the processing of PKCS#12 files from untrusted or unverified sources. Applications that use the `PKCS12_get_friendlyname()` API should ensure that PKCS#12 files are only processed if they originate from trusted entities. Restricting the input sources for PKCS#12 files can significantly reduce the attack surface for this flaw.

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).

Understanding the Weakness (CWE)

Integrity,Availability,Confidentiality

Technical Impact: DoS: Crash, Exit, or Restart; Execute Unauthorized Code or Commands; Read Memory; Modify Memory

If the incorrect calculation is used in the context of memory allocation, then the software may create a buffer that is smaller or larger than expected. If the allocated buffer is smaller than expected, this could lead to an out-of-bounds read or write (CWE-119), possibly causing a crash, allowing arbitrary code execution, or exposing sensitive data.
