Security Bulletin: Multiple Vulnerabilities in Go affects IBM Watson Studio Local

Vulnerability Details

CVEID:CVE-2019-11841
**DESCRIPTION:**A message-forgery issue was discovered in crypto/openpgp/clearsign/clearsign.go in supplementary Go cryptography libraries 2019-03-25. According to the OpenPGP Message Format specification in RFC 4880 chapter 7, a cleartext signed message can contain one or more optional “Hash” Armor Headers. The “Hash” Armor Header specifies the message digest algorithm(s) used for the signature. However, the Go clearsign package ignores the value of this header, which allows an attacker to spoof it. Consequently, an attacker can lead a victim to believe the signature was generated using a different message digest algorithm than what was actually used. Moreover, since the library skips Armor Header parsing in general, an attacker can not only embed arbitrary Armor Headers, but also prepend arbitrary text to cleartext messages without invalidating the signatures.

CVEID:CVE-2019-6486
**DESCRIPTION:**Go before 1.10.8 and 1.11.x before 1.11.5 mishandles P-521 and P-384 elliptic curves, which allows attackers to cause a denial of service (CPU consumption) or possibly conduct ECDH private key recovery attacks.

CVEID:CVE-2019-9741
**DESCRIPTION:**An issue was discovered in net/http in Go 1.11.5. CRLF injection is possible if the attacker controls a url parameter, as demonstrated by the second argument to http.NewRequest with \r\n followed by an HTTP header or a Redis command.

CVEID:CVE-2019-9634
**DESCRIPTION:**Go through 1.12 on Windows misuses certain LoadLibrary functionality, leading to DLL injection.

CVEID:CVE-2018-16874
**DESCRIPTION:**In Go before 1.10.6 and 1.11.x before 1.11.3, the “go get” command is vulnerable to directory traversal when executed with the import path of a malicious Go package which contains curly braces (both ‘{’ and ‘}’ characters). Specifically, it is only vulnerable in GOPATH mode, but not in module mode (the distinction is documented at <https://golang.org/cmd/go/#hdr-Module_aware_go_get&gt;). The attacker can cause an arbitrary filesystem write, which can lead to code execution.

CVEID:CVE-2018-16873
**DESCRIPTION:**In Go before 1.10.6 and 1.11.x before 1.11.3, the “go get” command is vulnerable to remote code execution when executed with the -u flag and the import path of a malicious Go package, or a package that imports it directly or indirectly. Specifically, it is only vulnerable in GOPATH mode, but not in module mode (the distinction is documented at <https://golang.org/cmd/go/#hdr-Module_aware_go_get&gt;). Using custom domains, it’s possible to arrange things so that a Git repository is cloned to a folder named “.git” by using a vanity import path that ends with “/.git”. If the Git repository root contains a “HEAD” file, a “config” file, an “objects” directory, a “refs” directory, with some work to ensure the proper ordering of operations, “go get -u” can be tricked into considering the parent directory as a repository root, and running Git commands on it. That will use the “config” file in the original Git repository root for its configuration, and if that config file contains malicious commands, they will execute on the system running “go get -u”.

CVEID:CVE-2018-16875
**DESCRIPTION:**The crypto/x509 package of Go before 1.10.6 and 1.11.x before 1.11.3 does not limit the amount of work performed for each chain verification, which might allow attackers to craft pathological inputs leading to a CPU denial of service. Go TLS servers accepting client certificates and TLS clients are affected.
