Description

openssl security update

OpenSSL is a robust, commercial-grade, and full-featured toolkit for the Transport Layer Security (TLS) and Secure Sockets Layer (SSL) protocols.

Security Fix(es):

Issue summary: Processing a maliciously formatted PKCS12 file may lead OpenSSL

to crash leading to a potential Denial of Service attack

Impact summary: Applications loading files in the PKCS12 format from untrusted

sources might terminate abruptly.

A file in PKCS12 format can contain certificates and keys and may come from an

untrusted source. The PKCS12 specification allows certain fields to be NULL, but

OpenSSL does not correctly check for this case. This can lead to a NULL pointer

dereference that results in OpenSSL crashing. If an application processes PKCS12

files from an untrusted source using the OpenSSL APIs then that application will

be vulnerable to this issue.

OpenSSL APIs that are vulnerable to this are: PKCS12_parse(),

PKCS12_unpack_p7data(), PKCS12_unpack_p7encdata(), PKCS12_unpack_authsafes()

and PKCS12_newpass().

We have also fixed a similar issue in SMIME_write_PKCS7(). However since this

function is related to writing data we do not consider it security significant.

The FIPS modules in 3.2, 3.1 and 3.0 are not affected by this issue.(CVE-2024-0727)

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is low, an attacker needs no privileges on the target. A user must be tricked into taking some action. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality none, integrity none, availability high.

CVSS metrics in full

The score comes from this vector: CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H

  • Attack vector: Local — a local account, shell or session on the host is needed.
  • Attack complexity: Low — the attack works reliably, with no preparation.
  • Privileges required: None — an unauthenticated stranger can try it.
  • User interaction: Required — someone has to click, open or visit something.
  • Scope: Unchanged — the damage stays inside the vulnerable component.
  • Confidentiality impact: None.
  • Integrity impact: None.
  • Availability impact: High — total loss, or loss the attacker controls.
