CVSS: 6.1EPSS: 0%CPEs: 6EXPL: 3CVE-2020-24553 – golang: default Content-Type setting in net/http/cgi and net/http/fcgi could cause XSS
https://notcve.org/view.php?id=CVE-2020-24553
Go before 1.14.8 and 1.15.x before 1.15.1 allows XSS because text/html is the default for CGI/FCGI handlers that lack a Content-Type header. Go versiones anteriores a 1.14.8 y versiones 1.15.x anteriores a 1.15.1, permite un ataque de tipo XSS porque text/html es el predeterminado para los manejadores de CGI/FCGI que carecen de un encabezado Content-Type A flaw was found in the Go standard library packages before upstream versions 1.15 and 1.14.8. Both the net/http/cgi and net/http/fcgi packages use a default Content-Type response header value of "text/html", rather than "text/plain". This flaw allows an attacker to exploit this issue in applications using these packages by uploading crafted files, allowing a Cross-site Scripting attack (XSS). The highest threat from this vulnerability is to confidentiality and integrity. • http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00002.html http://packetstormsecurity.com/files/159049/Go-CGI-FastCGI-Transport-Cross-Site-Scripting.html http://seclists.org/fulldisclosure/2020/Sep/5 https://groups.google.com/forum/#%21topic/golang-announce/8wqlSbkLdPs https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/CZBO7Q73GGWBVYIKNH2HNN44Q5IQND5W https://security.netapp.com/advisory • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •

https://notcve.org/view.php?id=CVE-2020-16845
Go before 1.13.15 and 14.x before 1.14.7 can have an infinite read loop in ReadUvarint and ReadVarint in encoding/binary via invalid inputs. Go versiones anteriores a 1.13.15 y versiones 14.x anteriores a 1.14.7, puede presentar un bucle de lectura infinito en las funciones ReadUvarint y ReadVarint en encoding/binary por medio de entradas no válidas A flaw was found in the Go encoding/binary package. Certain invalid inputs to the ReadUvarint or the ReadVarint causes those functions to read an unlimited number of bytes from the ByteReader argument before returning an error. This flaw possibly leads to processing more input than expected. The highest threat from this vulnerability is to system availability. • http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00021.html http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00028.html http://lists.opensuse.org/opensuse-security-announce/2020-09/msg00029.html http://lists.opensuse.org/opensuse-security-announce/2020-09/msg00030.html https://groups.google.com/forum/#%21topic/golang-announce/NyPIaucMgXo https://groups.google.com/forum/#%21topic/golang-announce/_ulYYcIWg3Q https://lists.debian.org/debian-lts-announce/2020/11/msg00037& • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •

Go before 1.13.13 and 1.14.x before 1.14.5 has a data race in some net/http servers, as demonstrated by the httputil.ReverseProxy Handler, because it reads a request body and writes a response at the same time.

Servers using ReverseProxy from net/http in the Go standard library are vulnerable to a data race that results in a denial of service.

CVSS: 7.5EPSS: 0%CPEs: 2EXPL: 0CVE-2020-14040 – golang.org/x/text: possibility to trigger an infinite loop in encoding/unicode could lead to crash
https://notcve.org/view.php?id=CVE-2020-14040
The x/text package before 0.3.3 for Go has a vulnerability in encoding/unicode that could lead to the UTF-16 decoder entering an infinite loop, causing the program to crash or run out of memory. An attacker could provide a single byte to a UTF16 decoder instantiated with UseBOM or ExpectBOM to trigger an infinite loop if the String function on the Decoder is called, or the Decoder is passed to golang.org/x/text/transform.String. El paquete x/text anterior a la versión 0.3.3 para Go tiene una vulnerabilidad en la codificación/unicode que podría llevar al decodificador UTF-16 a ingresar en un bucle infinito, causando que el programa se bloquee o se ejecute fuera de la memoria. Un atacante podría proporcionar un solo byte a un decodificador UTF16 instanciado con UseBOM o ExpectBOM para activar un bucle infinito si se llama a la función String en el Decoder, o el Decoder es pasado a golang.org/x/text/transform.String A denial of service vulnerability was found in the golang.org/x/text library. A library or application must use one of the vulnerable functions, such as unicode.Transform, transform.String, or transform.Byte, to be susceptible to this vulnerability. • https://groups.google.com/forum/#%21topic/golang-announce/bXVeAmGOqz0 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/TACQFZDPA7AUR6TRZBCX2RGRFSDYLI7O https://access.redhat.com/security/cve/CVE-2020-14040 https://bugzilla.redhat.com/show_bug.cgi?id=1853652 • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
