POP3: cURL and libcurl MD5 Digest Buffer Overflow
This signature detects attempts to exploit a known vulnerability in cURL and libcurl. A successful attack can lead to a buffer overflow and arbitrary remote code execution within the context of the server.
Extended Description
Stack-based buffer overflow in the Curl_sasl_create_digest_md5_message function in lib/curl_sasl.c in curl and libcurl 7.26.0 through 7.28.1, when negotiating SASL DIGEST-MD5 authentication, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a long string in the realm parameter in a (1) POP3, (2) SMTP or (3) IMAP message.
