SECUNIA ADVISORY ID: SA31036

VERIFY ADVISORY: link://[click]

CRITICAL: Moderately critical

IMPACT: DoS, System access

WHERE: From local network SOFTWARE: Novell eDirectory 8.x link://[click]

DESCRIPTION: A vulnerability has been reported in Novell eDirectory, which can be exploited by malicious people to cause a DoS (Denial of Service) or compromise a vulnerable system.

The vulnerability is caused due to an error in calculating the size of a heap buffer for storing LDAP search parameters. This can be exploited to cause a heap-based buffer overflow with the string "(null)" via NULL search parameters.

Successful exploitation may allow execution of arbitrary code.

The vulnerability affects version 8.8 and 8.7.3 on all platforms.

SOLUTION: Apply 8.8.2 FTF2 or 8.7.3.10b.
