Tavis Ormandy discovered that the SSH daemon did not properly handle authentication packets with duplicated blocks. By sending specially crafted packets, a remote attacker could exploit this to cause the ssh daemon to drain all available CPU resources until the login grace time
expired. (CVE-2006-4924) Mark Dowd discovered a race condition in the server's signal handling.
A remote attacker could exploit this to crash the server. (CVE-2006-5051)
Will Drewry, of the Google Security Team, discovered buffer overflows in GDB's DWARF processing. This would allow an attacker to execute arbitrary code with user privileges by tricking the user into using GDB to load an executable that contained malicious debugging
information.
Various flaws have been reported that allow an attacker to execute arbitrary code with user privileges by tricking the user into opening a malicious email containing JavaScript. Please note that JavaScript is disabled by default for emails, and it is not recommended to enable it.
