Hi,

The following vulnerability was published for openssl.

CVE-2024-0727[0]:
| 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.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
