Multiple integer overflows in the (1) curl_escape, (2) curl_easy_escape, (3) curl_unescape, and (4) curl_easy_unescape functions in libcurl before 7.50.3 allow attackers to have unspecified impact via a string of length 0xffffffff, which triggers a heap-based buffer overflow.

CVE-2016-7167 [CRITICAL] CWE-190 curl: escape and unescape integer overflows
curl: escape and unescape integer overflows
Multiple integer overflows in the (1) curl_escape, (2) curl_easy_escape, (3) curl_unescape, and (4) curl_easy_unescape functions in libcurl before 7.50.3 allow attackers to have unspecified impact via a string of length 0xffffffff, which triggers a heap-based buffer overflow.
Multiple integer overflow flaws leading to heap-based buffer overflows were found in the way curl handled escaping and unescaping of data. An attacker could potentially use these flaws to crash an application using libcurl by sending a specially crafted input to the affected libcurl functions.

CVE-2016-7167 [CRITICAL] CVE-2016-7167 curl: escape and unescape integer overflows
CVE-2016-7167 curl: escape and unescape integer overflows
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
