Description Tomas Hoger 2007-09-19 14:17:00 UTC

JosÃ© Miguel Esparza discovered that insufficient input validation is performed
on SIP protocol header field 'Content-Length' by opal library used by ekiga. 
This flaw can be used to write '\0' byte to attacker-controlled address and
crash ekiga.  Ekiga 2.0.10 using opal library 2.2.10 was released to address
this issue.

Ekiga 2.0.10 release notes:
