Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the 854c2afb-4424-11ed-af97-adcabf310f9b advisory.

- The Go project reports: archive/tar: unbounded memory consumption when reading headers Reader.Read did 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. Reader.Read now limits the maximum size of header blocks to 1 MiB. net/http/httputil: ReverseProxy should not forward unparseable query parameters Requests forwarded by ReverseProxy included 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. ReverseProxy will now sanitize 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.
regexp/syntax: limit memory used by parsing regexps 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. Each regexp being parsed is now limited to a 256 MB memory footprint. Regular expressions whose representation would use more space than that are now rejected. Normal use of regular expressions is unaffected. (CVE-2022-2879, CVE-2022-2880, CVE-2022-41715)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
