Synopsis ========
A buffer overflow in Echoping might allow remote attackers to cause a Denial of Service condition.
Background ==========
Echoping is a small program to test performances of a remote host by sending it TCP packets.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-analyzer/echoping < 6.0.2_p434 >= 6.0.2_p434
Description ===========
A boundary error exists within the "TLS_readline()" function, which can be exploited to overflow a global buffer by sending an overly long encrypted HTTP reply to Echoping. Also, a similar boundary error exists within the "SSL_readline()" function, which can be exploited in the same manner.
Impact ======
A remote attacker could send a specially crafted HTTP reply, possibly resulting in a Denial of Service condition.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All Echoping users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot -v ">=net-analyzer/echoping-6.0.2_p434"
