The encoding/xml package in Go (all versions) does not correctly preserve the semantics of element namespace prefixes during tokenization round-trips, which allows an attacker to craft inputs that behave in conflicting ways during different stages of processing in affected downstream applications.

An update of the kubernetes package has been released.

The remote Redhat Enterprise Linux 8 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - golang: crypto/elliptic implementations of P-521 and P-384 elliptic curves allow for denial of service     (CVE-2019-6486)

  - go: encoding/xml: XML element instability (CVE-2020-29511)

  - 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. (CVE-2020-14040)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - go: encoding/xml: XML element instability (CVE-2020-29511)

  - The encoding/xml package in Go (all versions) does not correctly preserve the semantics of attribute     namespace prefixes during tokenization round-trips, which allows an attacker to craft inputs that behave     in conflicting ways during different stages of processing in affected downstream applications.
    (CVE-2020-29509)

According to the versions of the golang packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - The encoding/xml package in Go (all versions) does not correctly preserve the semantics of attribute     namespace prefixes during tokenization round-trips, which allows an attacker to craft inputs that behave     in conflicting ways during different stages of processing in affected downstream applications.
    (CVE-2020-29509)

    (CVE-2020-29511)

  - The go command may generate unexpected code at build time when using cgo. This may result in unexpected     behavior when running a go program which uses cgo. This may occur when running an untrusted module which     contains directories with newline characters in their names. Modules which are retrieved using the go     command, i.e. via 'go get', are not affected (modules retrieved using GOPATH-mode, i.e. GO111MODULE=off,     may be affected). (CVE-2023-29402)

  - On Unix platforms, the Go runtime does not behave differently when a binary is run with the setuid/setgid     bits. This can be dangerous in certain cases, such as when dumping memory state, or assuming the status of     standard i/o file descriptors. If a setuid/setgid binary is executed with standard I/O file descriptors     closed, opening any files can result in unexpected content being read or written with elevated privileges.
    Similarly, if a setuid/setgid program is terminated, either via panic or signal, it may leak the contents     of its registers. (CVE-2023-29403)

  - The go command may execute arbitrary code at build time when using cgo. This may occur when running 'go     get' on a malicious module, or when running any other command which builds untrusted code. This is can by     triggered by linker flags, specified via a '#cgo LDFLAGS' directive. The arguments for a number of flags     which are non-optional are incorrectly considered optional, allowing disallowed flags to be smuggled     through the LDFLAGS sanitization. This affects usage of both the gc and gccgo compilers. (CVE-2023-29404)

  - The go command may execute arbitrary code at build time when using cgo. This may occur when running 'go     get' on a malicious module, or when running any other command which builds untrusted code. This is can by     triggered by linker flags, specified via a '#cgo LDFLAGS' directive. Flags containing embedded spaces are     mishandled, allowing disallowed flags to be smuggled through the LDFLAGS sanitization by including them in     the argument of another flag. This only affects usage of the gccgo compiler. (CVE-2023-29405)
