A denial of service vulnerability (CVE-2026-82397) exists in the python-tornado package used in Red Hat Enterprise Linux 9.6 Extended Update Support. The flaw allows denial of service via excessive URL-encoded body fields. Red Hat has issued an important security advisory with updated python-tornado packages to address this issue.
A synchronization issue in the Go standard library net/http package affects HTTP/1 servers using MaxBytesReader or MaxBytesHandler. When the MaxBytesReader limit is exceeded, the "Connection: close" header is set automatically without proper synchronization, which can race with other headers set explicitly by the server handler. This race condition can cause the server to crash due to a runtime panic if the handler reads the request body concurrently with writing the response header. Fixed versions 1.26.11 and 1.27.4 address this issue.
CVE-2026-97033 is a command injection vulnerability in the Go toolchain's cmd/go component related to the handling of cgo compiler and linker flags. Malicious packages using cgo could exploit certain flags to execute arbitrary code during build time. The vulnerability arises from unsafe use of flags such as --sysroot, -target, -isysroot, -Wl,-syslibroot, and -x in #cgo directives. The Go project has mitigated this by disallowing or restricting these flags and verifying their usage. Fixed versions are 1.26.11 and 1.27.4.
CVE-2026-97034 is a command injection vulnerability in the Go toolchain's cmd/go component when using GCC and cgo. It arises during the linking phase if malicious GCC spec files are present, potentially allowing arbitrary command execution. The vulnerability involves unsafe evaluation of GCC link specs when certain compiler flags like -fopenmp, -fopenacc, or -fsanitize= are used. The Go toolchain has been updated to reject directories containing GCC spec files and disallow certain flag prefixes to mitigate this risk.
CVE-2026-97035 is an argument injection vulnerability in the Go toolchain's cmd/go component affecting versions before 1.26.11 and between 1.27.0-0 and 1.27.4. It arises when building malicious packages using cgo with Clang or GCC compilers. The vulnerability allows unexpected code execution at build time or writing files to arbitrary directories via certain compiler and linker flags in #cgo directives. The issue stems from improper handling of "-gen-*" and "-gnat*" flags, which were previously allowed and could desynchronize argument parsing, enabling injection of unvalidated inputs to the linker. The flags "-gen-*" and "-gnat*" are now disallowed to mitigate this risk.
A vulnerability in the Go toolchain's cmd/go on Darwin platforms allows argument injection via malicious use of cgo with specific linker flags. This can lead to arbitrary code execution due to how the Apple linker recombines separated '-l' and 'to_library' arguments into a single flag that loads an arbitrary LTO plugin dynamic library at link time. The Go toolchain has been updated to disallow these dangerous linker flags and patterns to prevent exploitation.
CVE-2026-97037 is a code injection vulnerability in the Go toolchain's cmd/go component. It arises when building a malicious package that uses cgo, allowing arbitrary code execution at link time by passing linker script files to the host linker via "#cgo LDFLAGS". The vulnerability involves improper handling of certain "-Wl," flags that could be interpreted as linker scripts, leading to potential code execution. The issue is fixed in Go versions 1.26.11 and 1.27.4.
CVE-2026-97038 is a code injection vulnerability in the Go toolchain's cmd/go component. It allows building a malicious package with specially crafted ".syso" files or cgo linker inputs that can inject arbitrary linker flags or execute code during the linking phase. The vulnerability arises because linker input files were passed to the external linker without proper validation, enabling execution of disguised linker scripts or injection of unallowlisted linker flags across multiple platforms. The issue is fixed in Go versions 1.26.11 and 1.27.4.
CVE-2026-97039 is an argument injection vulnerability in the Go toolchain's cmd/go component. It involves malicious packages using "#cgo pkg-config:" directives to load untrusted pkg-config ".pc" files or inject unvalidated compiler and linker flags. The vulnerability arises from overly permissive allowlists for certain pkg-config flags and insufficient validation of flags returned by "pkg-config --cflags". The issue is addressed by disallowing specific flags and inspecting cgoCPPFLAGS for internal linking safety.
CVE-2026-97040 is a code injection vulnerability in the Go toolchain's cmd/go component. It allows an attacker to craft a ".syso" file that bypasses cgo flag validation and injects arbitrary linker flags during the linking process. This occurs because the linker incorrectly parses certain ".syso" files as Go compiler objects, allowing untrusted cgo metadata directives to be passed to the external linker without validation. The issue also involves improper handling of long ".syso" filenames, which can lose their extension and force external linking in pure-Go builds. The vulnerability is fixed in Go versions 1.26.11 and 1.27.4.
