Gentoo Linux Security Advisory
Title: Echoping: Buffer Overflow Vulnerabilities (GLSA 201406-07)
Severity: normal
Exploitable: remote
Date: June 06, 2014
Bug(s): #349569
ID: 201406-07
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: net-analyzer/echoping
Vulnerable: < 6.0.2_p434
Unaffected: >= 6.0.2_p434
Architectures: All supported architectures
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: Code: | # emerge --sync
# emerge --ask --oneshot --verbose
">=net-analyzer/echoping-6.0.2_p434"
|
