- Rename engines directories to the same name like in SLE:
/etc/ssl/engines1_1.d -> /etc/ssl/engines1.1.d
/etc/ssl/engdef1_1.d -> /etc/ssl/engdef1.1.d
* Add migration script to move files (bsc#1219562)
/etc/ssl/engines.d/* -> /etc/ssl/engines1.1.d
/etc/ssl/engdef.d/* -> /etc/ssl/engdef1.1.d
- Security fix: [bsc#1219243, CVE-2024-0727]
* Add NULL checks where ContentInfo data can be NULL
* Add openssl-CVE-2024-0727.patch

Subject: [PATCH] Add NULL checks where ContentInfo data can be NULL
|
|
|
|
PKCS12 structures contain PKCS7 ContentInfo fields. These fields are
|
|
optional and can be NULL even if the "type" is a valid value. OpenSSL
|
|
was not properly accounting for this and a NULL dereference can occur
|
|
causing a crash.
