Volema has reported a vulnerability in cURL / libcURL, which can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to a boundary error within the "Curl_sasl_create_digest_md5_message()" function (lib/curl_sasl.c) when negotiating SASL DIGEST-MD5 authentication and can be exploited to cause a stack-based buffer overflow.
Successful exploitation may allow execution of arbitrary code but requires tricking a user into connecting to a malicious server.
The vulnerability is reported in versions 7.26.0 through 7.28.1.
Solution: Update to version 7.29.0.
