TITLE

OpenSSL  Double release vulnerability in

DESCRIPTION

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. OpenSSL has payload data 0 become a part-time worker PEM When creating a file, PEM_read_bio_ex() A double free vulnerability exists because when returns a failure code, it introduces a pointer to an already freed buffer into the header argument.Malicious by attacker PEM Denial of service by providing files ( crash ) It may be in a state. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: openssl security and bug fix update Advisory ID: RHSA-2023:0946-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2023:0946 Issue date: 2023-02-28 CVE Names: CVE-2022-4203 CVE-2022-4304 CVE-2022-4450 CVE-2023-0215 CVE-2023-0216 CVE-2023-0217 CVE-2023-0286 CVE-2023-0401 ===================================================================== 1.
