CVE-2024-1454

Description

The use-after-free vulnerability was found in the AuthentIC driver in OpenSC packages, occuring in the card enrolment process using pkcs15-init when a user or administrator enrols or modifies cards. An attacker must have physical access to the computer system and requires a crafted USB device or smart card to present the system with specially crafted responses to the APDUs, which are considered high complexity and low severity. This manipulation can allow for compromised card management operations during enrolment.

Statement

The opensc package versions, as shipped with Red Hat Enterprise Linux 7, 8, and 9, are not affected by this vulnerability, as the vulnerable upstream source code was not backported to any of these products.

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.

Understanding the Weakness (CWE)

Integrity

Technical Impact: Modify Memory

The use of previously freed memory may corrupt valid data, if the memory area in question has been allocated and used properly elsewhere.

Availability

Technical Impact: DoS: Crash, Exit, or Restart

If chunk consolidation occurs after the use of previously freed data, the process may crash when invalid data is used as chunk information.

Confidentiality

Technical Impact: Read Memory

Read operations on freed memory can sometimes leak sensitive information instead of causing a crash

Integrity,Confidentiality,Availability

Technical Impact: Execute Unauthorized Code or Commands

If malicious data is entered before chunk consolidation can take place, it may be possible to take advantage of a write-what-where primitive to execute arbitrary code. If the newly allocated data happens to hold a class, in C++ for example, various function pointers may be scattered within the heap data. If one of these function pointers is overwritten with an address to valid shellcode, execution of arbitrary code can be achieved.
