Invoking Encrypted Client Hello privacy leak in crypto/tls
Handshakes which used Encrypted Client Hello could be de-anonymized by a passive network observer due to a disclosure of pre-shared key identities in the unencrypted client hello.

Handshake messages may be processed at the incorrect encryption level in crypto/tls
During the TLS 1.3 handshake if multiple messages are sent in records that span encryption level boundaries (for instance the Client Hello and Encrypted Extensions messages), the subsequent messages may be processed before the encryption level changes. This c…

Malformed constraint may cause denial of service in golang.org/x/crypto/ssh/agent
SSH Agent servers do not validate the size of messages when processing new identity requests, which may cause the program to panic if the message is malformed due to an out of bounds read.

Excessive CPU consumption in Reader.ReadResponse in net/textproto
The Reader.ReadResponse function constructs a response string through repeated string concatenation of lines. When the number of lines in a response is large, this can cause excessive CPU consumption.

Unbounded allocation when parsing GNU sparse map in archive/tar
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 archiv…

Parsing DER payload can cause memory exhaustion in encoding/asn1
Parsing a maliciously crafted DER payload could allocate large amounts of memory, causing memory exhaustion.

Lack of limit when parsing cookies can cause memory exhaustion in net/http
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 mem…

Insufficient validation of bracketed IPv6 hostnames in net/url
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://[…

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

CrossOriginProtection insecure bypass patterns not limited to exact matches in net/http
When using http.CrossOriginProtection, the AddInsecureBypassPattern method can unexpectedly bypass more requests than intended. CrossOriginProtection then skips validation, but forwards the original request path, which may be served by a different handler wit…

Sensitive headers not cleared on cross-origin redirect in net/http
Proxy-Authorization and Proxy-Authenticate headers persisted on cross-origin redirects potentially leaking sensitive information.

Timing sidechannel for P-256 on ppc64le in crypto/internal/nistec
Due to the usage of a variable time instruction in the assembly implementation of an internal function, a small number of bits of secret scalars are leaked on the ppc64le architecture. Due to the way this function is used, we do not believe this leakage is en…

Sensitive headers incorrectly sent after cross-domain redirect in net/http
The HTTP client drops sensitive headers after following a cross-domain redirect. For example, a request to a.com/ containing an Authorization header which is redirected to b.com/ will not send that header to b.com. In the event that the client received a subs…

Usage of IPv6 zone IDs can bypass URI name constraints in crypto/x509
A certificate with a URI which has a IPv6 address with a zone ID may incorrectly satisfy a URI name constraint that applies to the certificate chain. Certificates containing URIs are not permitted in the web PKI, so this only affects users of private PKIs whi…

Stack exhaustion in all Parse functions in go/parser
Calling any of the Parse functions on Go source code which contains deeply nested literals can cause a panic due to stack exhaustion.

Mishandling of corrupt central directory record in archive/zip
The archive/zip package's handling of certain types of invalid zip files differs from the behavior of most zip implementations. This misalignment could be exploited to create an zip file with contents that vary depending on the implementation reading the file…

Arbitrary code execution during build on Darwin in cmd/go
On Darwin, building a Go module which contains CGO can trigger arbitrary code execution when using the Apple version of ld, due to usage of the -lto_library flag in a "#cgo LDFLAGS" directive.

Malformed DNS message can cause infinite loop in net
A malformed DNS message in response to a query can cause the Lookup functions to get stuck in an infinite loop.
