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.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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.
    (CVE-2020-29511)

Note that Nessus relies on the presence of the package as reported by the vendor.

An update of the kubernetes package has been released.

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)

  - 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.
    (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)

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - 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)

  - 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.
    (CVE-2020-29511)

  - Go before 1.17 does not properly consider extraneous zero characters at the beginning of an IP address
    octet, which (in some situations) allows attackers to bypass access control that is based on IP addresses,
    because of unexpected octal interpretation. This affects net.ParseIP and net.ParseCIDR. (CVE-2021-29923)
