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.

  - gcc: integer overflow flaws in libgfortran (CVE-2014-5044)

  - The std::random_device class in libstdc++ in the GNU Compiler Collection (aka GCC) before 4.9.4 does not     properly handle short reads from blocking sources, which makes it easier for context-dependent attackers     to predict the random values via unspecified vectors. (CVE-2015-5276)

  - Integer overflow in the string_appends function in cplus-dem.c in libiberty allows remote attackers to     execute arbitrary code via a crafted executable, which triggers a buffer overflow. (CVE-2016-2226)

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

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

  - Some HTTP/2 implementations are vulnerable to ping     floods, potentially leading to a denial of service. The     attacker sends continual pings to an HTTP/2 peer,     causing the peer to build an internal queue of     responses. Depending on how efficiently this data is     queued, this can consume excess CPU, memory, or     both.(CVE-2019-9512)

  - Some HTTP/2 implementations are vulnerable to a reset     flood, potentially leading to a denial of service. The     attacker opens a number of streams and sends an invalid     request over each stream that should solicit a stream     of RST_STREAM frames from the peer. Depending on how     the peer queues the RST_STREAM frames, this can consume     excess memory, CPU, or both.(CVE-2019-9514)

  - 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.(CVE-2020-16845)

  - 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.(CVE-2020-24553)

go1.15 (released 2020-08-11) Go 1.15 is a major release of Go.

go1.15.x minor releases will be provided through August 2021.

https://github.com/golang/go/wiki/Go-Release-Cycle

Most changes are in the implementation of the toolchain, runtime, and libraries. As always, the release maintains the Go 1 promise of compatibility. We expect almost all Go programs to continue to compile and run as before.

See release notes https://golang.org/doc/go1.15. Excerpts relevant to OBS environment and for SUSE/openSUSE follow :

Module support in the go command is ready for production use, and we encourage all users to migrate to Go modules for dependency management.

Module cache: The location of the module cache may now be set with the GOMODCACHE environment variable. The default value of GOMODCACHE is GOPATH[0]/pkg/mod, the location of the module cache before this change.

Compiler flag parsing: Various flag parsing issues in go test and go vet have been fixed. Notably, flags specified in GOFLAGS are handled more consistently, and the -outputdir flag now interprets relative paths relative to the working directory of the go command (rather than the working directory of each individual test).

The GOPROXY environment variable now supports skipping proxies that return errors. Proxy URLs may now be separated with either commas (,) or pipe characters (|). If a proxy URL is followed by a comma, the go command will only try the next proxy in the list after a 404 or 410 HTTP response. If a proxy URL is followed by a pipe character, the go command will try the next proxy in the list after any error. Note that the default value of GOPROXY remains https://proxy.golang.org,direct, which does not fall back to direct in case of errors.

On a Unix system, if the kill command or kill system call is used to send a SIGSEGV, SIGBUS, or SIGFPE signal to a Go program, and if the signal is not being handled via os/signal.Notify, the Go program will now reliably crash with a stack trace. In earlier releases the behavior was unpredictable.

Allocation of small objects now performs much better at high core counts, and has lower worst-case latency.

Go 1.15 reduces typical binary sizes by around 5% compared to Go 1.14 by eliminating certain types of GC metadata and more aggressively eliminating unused type metadata.

The toolchain now mitigates Intel CPU erratum SKX102 on GOARCH=amd64 by aligning functions to 32 byte boundaries and padding jump instructions. While this padding increases binary sizes, this is more than made up for by the binary size improvements mentioned above.

Go 1.15 adds a -spectre flag to both the compiler and the assembler, to allow enabling Spectre mitigations. These should almost never be needed and are provided mainly as a 'defense in depth' mechanism. See the Spectre Go wiki page for details.

The compiler now rejects //go: compiler directives that have no meaning for the declaration they are applied to with a 'misplaced compiler directive' error. Such misapplied directives were broken before, but were silently ignored by the compiler.

Substantial improvements to the Go linker, which reduce linker resource usage (both time and memory) and improve code robustness/maintainability. Linking is 20% faster and requires 30% less memory on average. These changes are part of a multi-release project to modernize the Go linker, meaning that there will be additional linker improvements expected in future releases.

The linker now defaults to internal linking mode for

-buildmode=pie on linux/amd64 and linux/arm64, so these configurations no longer require a C linker.

There has been progress in improving the stability and performance of the 64-bit RISC-V port on Linux (GOOS=linux, GOARCH=riscv64). It also now supports asynchronous preemption.

crypto/x509: The deprecated, legacy behavior of treating the CommonName field on X.509 certificates as a host name when no Subject Alternative Names are present is now disabled by default. It can be temporarily re-enabled by adding the value x509ignoreCN=0 to the GODEBUG environment variable. Note that if the CommonName is an invalid host name, it's always ignored, regardless of GODEBUG settings. Invalid names include those with any characters other than letters, digits, hyphens and underscores, and those with empty labels or trailing dots.

crypto/x509: go1.15 applications with an AWS DB instance that was created or updated to the rds-ca-2019 certificate prior to July 28, 2020, you must update the certificate again. If you created your DB instance or updated its certificate after July 28, 2020, no action is required. For more information, see go#39568

The Go project reports :

When a Handler does not explicitly set the Content-Type header, both CGI implementations default to 'text/html'. If an attacker can make a server generate content under their control (e.g. a JSON containing user data or an uploaded image file) this might be mistakenly returned by the server as 'text/html'. If a victim visits such a page they could get the attacker's code executed in the context of the server origin.
