Design/Logic Flaw

The public API function BIOnewNDEF is a helper function used for streaming ASN.1 data via a BIO. It is primarily used internally to OpenSSL to support the SMIME, CMS and PKCS7 streaming capabilities, but may also be called directly by end user applications. The function receives a BIO from the...

Null pointer dereference

An invalid pointer dereference on read can be triggered when an application tries to load malformed PKCS7 data with the d2iPKCS7, d2iPKCS7bio or d2iPKCS7fp functions. The result of the dereference is an application crash which could lead to a denial of service attack. The TLS implementation in...

CVE-2023-25165 getHostByName Function Information Disclosure

Helm is a tool that streamlines installing and managing Kubernetes applications.getHostByName is a Helm template function introduced in Helm v3. The function is able to accept a hostname and return an IP address for that hostname. To get the IP address the function performs a DNS lookup. The DNS...

CVE-2023-0215

CVE-2023-0215 describes a use-after-free in OpenSSL’s BIO_new_NDEF path used with SMIME/CMS/PKCS7 streaming. When a CMS recipient key is invalid, the filter BIO is freed but the caller’s BIO still holds pointers, allowing use-after-free on BIO_pop(); this can crash the process. Affected internal ...

CVE-2023-0216 Invalid pointer dereference in d2i_PKCS7 functions

An invalid pointer dereference on read can be triggered when an application tries to load malformed PKCS7 data with the d2iPKCS7, d2iPKCS7bio or d2iPKCS7fp functions. The result of the dereference is an application crash which could lead to a denial of service attack. The TLS implementation in...

CVE-2023-0216

CVE-2023-0216 : OpenSSL contains an invalid pointer dereference on read when an application loads malformed PKCS7 data via d2i_PKCS7(), d2i_PKCS7_bio(), or d2i_PKCS7_fp(). This can cause an application crash and potentially a denial of service. The description notes that the TLS implementation it...

google-oauth-client: missing PKCE support in accordance with the RFC for OAuth 2.0 for Native Apps can lead to improper authorization

PKCE support is not implemented in accordance with the RFC for OAuth 2.0 for Native Apps. Without the use of PKCE, the authorization code returned by an authorization server is not enough to guarantee that the client that issued the initial authorization request is the one that will be authorized...
