### Impact User-provided strings to formula's parser might lead to polynomial execution time. ### Patches Users should upgrade to 3.0.1+. ### Workarounds None.

### Impact The [v0.38.0](https://github.com/open-telemetry/opentelemetry-go-contrib/releases/tag/v1.13.0) release of [`go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp`](https://github.com/open-telemetry/opentelemetry-go-contrib/blob/463c2e7cd69d25f40b0a595b05394eeb26c68ae2/instrumentation/net/http/otelhttp/handler.go#L218) uses the [`httpconv.ServerRequest`](https://github.com/open-telemetry/opentelemetry-go/blob/v1.12.0/semconv/internal/v2/http.go#L159) function to annotate metric measurements for the `http.server.request_content_length`, `http.server.response_content_length`, and `http.server.duration` instruments. The `ServerRequest` function sets the `http.target` attribute value to be the whole request URI (including the query string)[^1]. The metric instruments do not "forget" previous measurement attributes when `cumulative` temporality is used, this means the cardinality of the measurements allocated is directly correlated with the unique URIs handled. If the qu...

A read buffer overrun can be triggered in X.509 certificate verification, specifically in name constraint checking. Note that this occurs after certificate chain signature verification and requires either a CA to have signed the malicious certificate or for the application to continue certificate verification despite failure to construct a path to a trusted issuer. The read buffer overrun might result in a crash which could lead to a denial of service attack. In theory it could also result in the disclosure of private memory contents (such as private keys, or sensitive plaintext) although we are not aware of any working exploit leading to memory contents disclosure as of the time of release of this advisory. In a TLS client, this can be triggered by connecting to a malicious server. In a TLS server, this can be triggered if the server requests client authentication and a malicious client connects.

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.

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. The...
