TITLE:
IMail Server LDAP Daemon Buffer Overflow Vulnerability
SECUNIA ADVISORY ID:
SA10880
VERIFY ADVISORY:
http://secunia.com/advisories/10880/
CRITICAL:
Highly critical
IMPACT:
System access
WHERE:
From remote
SOFTWARE:
IMail Server 7.x
IMail Server 8.x
DESCRIPTION:
iDEFENSE has reported a vulnerability in IMail Server, which can be
exploited by malicious people to compromise a vulnerable system.
The vulnerability is caused due to a boundary error in the LDAP
daemon ("iLDAP.exe") when handling tags in LDAP messages. This can be
exploited to cause a buffer overflow prior to authentication by
sending specially crafted LDAP messages with overly long length tags
to a vulnerable system.
Successful exploitation allows execution of arbitrary code.
The vulnerability has been reported in "iLDAP.exe" 3.9.15.10 included
in IMail Server 8.03. However, other versions may also be affected.
SOLUTION:
Apply 8.05 Hotfix 2.
