An update for golang is now available for HCE 2.0 Security Advisory hws_security@huawei.com Huawei Cloud HCE2-SA-2023-0082 Final 1.0 1.0 2023-01-05T20:19:38:00Z current version 2023-01-05T20:19:38:00Z 2023-01-05T20:19:38:00Z HCE SA Engine 1.0.0 An update for golang is now available for HCE 2.0 HCE Security has rated this update as having a security impact of Important.A Common Vunlnerability Scoring System(CVSS)base score, which gives a detailed severity rating, is available for each vulnerability from the CVElink(s) in the References section. Security Fix(es): Programs which compile regular expressions from untrusted sources may be vulnerable to memory exhaustion or denial of service. The parsed regexp representation is linear in the size of the input, but in some cases the constant factor can be as high as 40,000, making relatively small regexps consume much larger amounts of memory. After fix, each regexp being parsed is limited to a 256 MB memory footprint. Regular expressions whose representation would use more space than that are rejected. Normal use of regular expressions is unaffected. (CVE-2022-41715) Due to unsanitized NUL values, attackers may be able to maliciously set environment variables on Windows. In syscall.StartProcess and os/exec.Cmd, invalid environment variable values containing NUL values are not properly checked for. A malicious environment variable value can exploit this behavior to set a value for a different environment variable. For example, the environment variable string "A=B\x00C=D" sets the variables "A=B" and "C=D". (CVE-2022-41716) Reader.Read does not set a limit on the maximum size of file headers. A maliciously crafted archive could cause Read to allocate unbounded amounts of memory, potentially causing resource exhaustion or panics. After fix, Reader.Read limits the maximum size of header blocks to 1 MiB. (CVE-2022-2879) An attacker can cause excessive memory growth in a Go server accepting HTTP/2 requests. HTTP/2 server connections contain a cache of HTTP header keys sent by the client. While the total number of entries in this cache is capped, an attacker sending very large keys can cause the server to allocate approximately 64 MiB per open connection. (CVE-2022-41717) Requests forwarded by ReverseProxy include the raw query parameters from the inbound request, including unparseable parameters rejected by net/http. This could permit query parameter smuggling when a Go proxy forwards a parameter with an unparseable value. After fix, ReverseProxy sanitizes the query parameters in the forwarded query when the outbound request's Form field is set after the ReverseProxy. Director function returns, indicating that the proxy has parsed the query parameters. Proxies which do not parse query parameters continue to forward the original query parameters unchanged.
