CVE-2018-0500: Buffer Overflow
First published: Mon Jul 02 2018(Updated: )
curl versions 7.54.1 through 7.60.0 are vulnerable to a heap-based buffer overflow in the Curl_smtp_escape_eob() function when uploading data over SMTP and using a reduced read buffer. An attacker could exploit this by convincing a user to use curl to upload data over SMTP with a reduced buffer to cause a crash or corrupt memory.
