CVE-2024-0727

A flaw was found in OpenSSL. The optional ContentInfo fields can be set to null, even if the "type" is a valid value, which can lead to a null dereference error that may cause a denial of service.

This vulnerability is classified as low severity. This is a result of a lack of proper validation in OpenSSL's handling of PKCS12 files. This vulnerability results in a potential Denial of Service scenario wherein maliciously crafted PKCS12 files may cause OpenSSL to crash due to a NULL pointer dereference. However, the impact of this issue is reduced by the fact that exploitation requires processing PKCS12 files from untrusted sources using specific OpenSSL APIs, such as PKCS12_parse(), PKCS12_unpack_p7data(), PKCS12_unpack_p7encdata(), PKCS12_unpack_authsafes(), and PKCS12_newpass(). Furthermore, while a similar issue was addressed in SMIME_write_PKCS7(), its relevance is diminished as it pertains to writing data rather than parsing, hence not considered security significant. The risk of this vulnerability is limited as Red Hat offerings do not utilize images from untrusted sources by default.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
