GHSA-V5W6-WCM8-JM4Q openssl-src contains Double free after calling `PEM_read_bio_ex`

The function PEMreadbioex reads a PEM file from a BIO and parses and decodes the "name" e.g. "CERTIFICATE", any header data and the payload data. If the function succeeds then the "nameout", "header" and "data" arguments are populated with pointers to buffers containing the relevant decoded data...

CVE-2022-4450

Summary (CVE-2022-4450): OpenSSL’s PEM_read_bio_ex() and wrappers PEM_read_bio()/PEM_read() are vulnerable. If a PEM file is crafted to trigger a 0-byte payload, PEM_read_bio_ex() may return a failure while its header buffer has already been freed; freeing that buffer again can cause a use-after-...

Amazon Linux 2 : openssl11 (ALAS-2023-1934)

The version of openssl11 installed on the remote host is prior to 1.1.1g-12. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2023-1934 advisory. A timing-based side channel exists in the OpenSSL RSA Decryption implementation, which could be sufficient to recover ...
