There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - A flaw was found in CIRCL's implementation of the FourQ elliptic curve. This vulnerability allows an
    attacker to compromise session security via low-order point injection and incorrect point validation
    during Diffie-Hellman key exchange. (CVE-2025-8556)

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2025-1359 advisory.

    Calling Verify with a VerifyOptions.KeyUsages that contains ExtKeyUsageAny unintentionally disabledpolicy     validation. This only affected certificate chains which contain policy graphs, which are rather uncommon.
    (CVE-2025-22874)

    Proxy-Authorization and Proxy-Authenticate headers persisted on cross-origin redirects potentially leaking     sensitive information. (CVE-2025-4673)

    net/url: insufficient validation of bracketed IPv6 hostnames

    The Parse function permitted 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 must not     appear within square brackets. Parse did not enforce this requirement. (CVE-2025-47912)

    archive/tar: unbounded allocation when parsing GNU sparse map

    tar.Reader did 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 could cause a Reader to     read an unbounded amount of data from the archive into memory. When reading from a compressed source, a     small compressed input could result in large allocations. (CVE-2025-58183)

    encoding/asn1: pre-allocating memory when parsing DER payload can cause memory exhaustion

    When parsing DER payloads, memories were being allocated prior to fully validating the payloads.This     permits an attacker to craft a big empty DER payload to cause memory exhaustion in functions such as     asn1.Unmarshal, x509.ParseCertificateRequest, and ocsp.ParseResponse. (CVE-2025-58185)

    net/http: lack of limit when parsing cookies can cause memory exhaustion

    Despite HTTP headers having a default limit of 1 MB, the number of cookies that can be parsed did 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.

    net/http now limits the number of cookies accepted to 3000, which can be adjusted using the     httpcookiemaxnum GODEBUG option. (CVE-2025-58186)

    crypto/x509: quadratic complexity when checking name constraints

    Due to the design of the name constraint checking algorithm, the processing timeof some inputs scales non-     linearly with respect to the size of the certificate.

    This affects programs which validate arbitrary certificate chains. (CVE-2025-58187)

    crypto/x509: panic when validating certificates with DSA public keys

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

    This affects programs which validate arbitrary certificate chains. (CVE-2025-58188)

    crypto/tls: ALPN negotiation errors can contain arbitrary text

    The crypto/tls conn.Handshake method returns an error on the server-side when ALPN negotation fails which     can contain arbitrary attacker controlled information provided by the client-side of the connection which     is not escaped.

    This affects programs which log these errors without any additional form of sanitization, and may allow     injection of attacker controlled information into logs. (CVE-2025-58189)

    encoding/pem: quadratic complexity when parsing some invalid inputs

    Due to the design of the PEM parsing function, the processing time for someinputs scales non-linearly with     respect to the size of the input.

    This affects programs which parse untrusted PEM inputs. (CVE-2025-61723)

    net/textproto: excessive CPU consumption in Reader.ReadResponse

    The Reader.ReadResponse function constructed a response string throughrepeated string concatenation of     lines. When the number of lines in a response is large,this could cause excessive CPU consumption.
    (CVE-2025-61724)

    net/mail: excessive CPU consumption in ParseAddress

    The ParseAddress function constructed domain-literal address components through repeated string     concatenation. When parsing large domain-literal components, this could cause excessive CPU consumption.
    (CVE-2025-61725)

    crypto/x509: excluded subdomain constraint does not restrict wildcard SANs

    An excluded subdomain constraint in a certificate chain does not restrict the usage of wildcard SANs in     the leaf certificate. For example a constraint that excludes the subdomain test.example.com does not     prevent a leaf certificate from claiming the SAN *.example.com. (CVE-2025-61727)

    Within HostnameError.Error(), when constructing an error string, there is no limit to the number of hosts     that will be printed out. Furthermore, the error string is constructed by repeated string concatenation,     leading to quadratic runtime. Therefore, a certificate provided by a malicious actor can result in     excessive resource consumption. (CVE-2025-61729)

    A flaw was found in CIRCL's implementation of the FourQ elliptic curve. This vulnerability allows an     attacker to compromise session security via low-order point injection and incorrect point validation     during Diffie-Hellman key exchange. (CVE-2025-8556)
