VUL-1: CVE-2016-7167: curl: escape and unescape integer overflows
Last modified: 2018-09-05 11:06:29 UTC
rh#1375906 It was found that provided string length arguments in four libcurl functions curl_escape(), curl_easy_escape(), curl_unescape and curl_easy_unescape were not properly checked and due to arithmetic in the functions, passing in the length 0xffffffff (2^32-1 or UINT_MAX or even just -1) would end up causing an allocation of zero bytes of heap memory that curl would attempt to write gigabytes of data into. This flaw does not affect the curl command line tool. Affected versions: libcurl 7.11.1 to and including 7.50.2 External References: References: https://curl.haxx.se/docs/adv_20160914.html https://curl.haxx.se/CVE-2016-7167.patch https://bugzilla.redhat.com/show_bug.cgi?id=1375906 http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2016-7167 http://seclists.org/oss-sec/2016/q3/498 https://bugs.php.net/bug.php?id=72674
