Validating certificate chains which contain DSA public keys can cause programs to panic, due to a interface cast that assumes they implement the Equal method. This affects programs which validate arbitrary certificate chains.

tar.Reader does not set a maximum size on the number of sparse region data blocks in GNU tar pax 1.0 sparse files. A maliciously-crafted archive containing a large number of sparse regions can cause a Reader to read an unbounded amount of data from the archive into memory. When reading from a compr…

Despite HTTP headers having a default limit of 1MB, the number of cookies that can be parsed does not have a limit. By sending a lot of very small cookies such as "a=;", an attacker can make an HTTP server allocate a large amount of structs, causing large memory consumption.

The Parse function permits values other than IPv6 addresses to be included in square brackets within the host component of a URL. RFC 3986 permits IPv6 addresses to be included within the host component, enclosed within square brackets. For example: "http://[::1]/". IPv4 addresses and hostnames mus…

The processing time for parsing some invalid inputs scales non-linearly with respect to the size of the input. This affects programs which parse untrusted PEM inputs.

Parsing a maliciously crafted DER payload could allocate large amounts of memory, causing memory exhaustion.

Due to the design of the name constraint checking algorithm, the processing time of some inputs scals non-linearly with respect to the size of the certificate. This affects programs which validate arbitrary certificate chains.

When Conn.Handshake fails during ALPN negotiation the error contains attacker controlled information (the ALPN protocols sent by the client) which is not escaped.

The ParseAddress function constructeds domain-literal address components through repeated string concatenation. When parsing large domain-literal components, this can cause excessive CPU consumption.

Prior to September 19, 2025, the Hospital Manager Backend Services returned verbose ASP.NET error pages for invalid WebResource.axd requests, disclosing framework and ASP.NET version information, stack traces, internal paths, and the insecure configuration 'customErrors mode="Off"', which could hav…
