Security information¶

Resolved CVEs, as detailed:

CVE	Status	Problem details from upstream
CVE-2023-0401	Resolved	A NULL pointer can be dereferenced when signatures are being verified on PKCS7 signed or signedAndEnveloped data. In case the hash algorithm used for the signature is known to the OpenSSL library but the implementation of the hash algorithm is not available the digest initialization will fail. There is a missing check for the return value from the initialization function which later leads to invalid usage of the digest API most likely leading to a crash. The unavailability of an algorithm can be caused by using FIPS enabled configuration of providers or more commonly by not loading the legacy provider. PKCS7 data is processed by the SMIME library calls and also by the time stamp (TS) library calls. The TLS implementation in OpenSSL does not call these functions however third party applications would be affected if they call these functions to verify signatures on untrusted data.
CVE-2023-0217	Resolved	An invalid pointer dereference on read can be triggered when an application tries to check a malformed DSA public key by the `EVP_PKEY_public_check()` function. This will most likely lead to an application crash. This function can be called on public keys supplied from untrusted sources which could allow an attacker to cause a denial of service attack. The TLS implementation in OpenSSL does not call this function but applications might call the function if there are additional security requirements imposed by standards such as FIPS 140-3.
CVE-2023-0216	Resolved	An invalid pointer dereference on read can be triggered when an application tries to load malformed PKCS7 data with the `d2i_PKCS7()`, `d2i_PKCS7_bio()` or `d2i_PKCS7_fp()` functions. The result of the dereference is an application crash which could lead to a denial of service attack. The TLS implementation in OpenSSL does not call this function however third party applications might call these functions on untrusted data.
CVE-2022-41862	Resolved	In PostgreSQL, a modified, unauthenticated server can send an unterminated string during the establishment of Kerberos transport encryption. In certain conditions a server can cause a libpq client to over-read and report an error message containing uninitialized bytes.
CVE-2022-3996	Resolved	If an X.509 certificate contains a malformed policy constraint and policy processing is enabled, then a write lock will be taken twice recursively. On some operating systems (most widely: Windows) this results in a denial of service when the affected process hangs. Policy processing being enabled on a publicly facing server is not considered to be a common setup. Policy processing is enabled by passing the `-policy` argument to the command line utilities or by calling the `X509_VERIFY_PARAM_set1_policies()` function. Update (31 March 2023): The description of the policy processing enablement was corrected based on CVE-2023-0466.
CVE-2017-9225	False positive	An issue was discovered in Oniguruma 6.2.0, as used in Oniguruma-mod in Ruby through 2.4.1 and mbstring in PHP through 7.1.5. A stack out-of-bounds write in `onigenc_unicode_get_case_fold_codes_by_str()` occurs during regular expression compilation. Code point `0xFFFFFFFF` is not properly handled in `unicode_unfold_key()`. A malformed regular expression could result in 4 bytes being written off the end of a stack buffer of `expand_case_fold_string()` during the call to `onigenc_unicode_get_case_fold_codes_by_str()`, a typical stack buffer overflow.
