CBL Mariner 2.0 Security Update: edk2 / hvloader / cloud-hypervisor / rust / openssl (CVE-2022-4450)

high Nessus Plugin ID 201612

Synopsis

The remote CBL Mariner host is missing one or more security updates.

Description

The version of edk2 / hvloader / cloud-hypervisor / rust / openssl installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2022-4450 advisory.

 - The function PEM_read_bio_ex() 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 name_out, header and data arguments are populated with pointers to buffers containing the relevant decoded data.
 The caller is responsible for freeing those buffers. It is possible to construct a PEM file that results in 0 bytes of payload data. In this case PEM_read_bio_ex() will return a failure code but will populate the header argument with a pointer to a buffer that has already been freed. If the caller also frees this buffer then a double free will occur. This will most likely lead to a crash. This could be exploited by an attacker who has the ability to supply malicious PEM files for parsing to achieve a denial of service attack. The functions PEM_read_bio() and PEM_read() are simple wrappers around PEM_read_bio_ex() and therefore these functions are also directly affected. These functions are also called indirectly by a number of other OpenSSL functions including PEM_X509_INFO_read_bio_ex() and SSL_CTX_use_serverinfo_file() which are also vulnerable. Some OpenSSL internal uses of these functions are not vulnerable because the caller does not free the header argument if PEM_read_bio_ex() returns a failure code. These locations include the PEM_read_bio_TYPE() functions as well as the decoders introduced in OpenSSL 3.0. The OpenSSL asn1parse command line application is also impacted by this issue. (CVE-2022-4450)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
