Subject: fix: dev: Improve the input validation of the isc_url_parse() function
X-Git-Url: http://git.ipfire.org/gitweb/?a=commitdiff_plain;h=d960de55be68f499be29841a05015bdf8428e4b5;p=thirdparty%2Fbind9.git

fix: dev: Improve the input validation of the isc_url_parse() function

The isc_url_parse() function failed to check the input buffer's
length and assumed that it can't be bigger than UINT16_MAX, because
both the 'off' and 'len' fields of the 'isc_url_parser_t' structure
are uint16_t.

Add a check to not accept a buffer longer than 8192 octets.

Closes #6150

Merge branch '6150-isc_url_parse-buffer-size-check-fix' into 'main'
