Summaryinfo

A vulnerability identified as problematic has been detected in FreeBSD 4.4. Affected by this issue is some unknown functionality of the component AIO Handler. Performing a manipulation results in memory corruption. This vulnerability was named CVE-2001-1185. In addition, an exploit is available. It is suggested to use restrictive firewalling.

Detailsinfo

A vulnerability, which was classified as critical, was found in FreeBSD 4.4 (Operating System). This affects some unknown functionality of the component AIO Handler. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Some AIO operations in FreeBSD 4.4 may be delayed until after a call to execve, which could allow a local user to overwrite memory of the new process and gain privileges.

The weakness was presented 12/10/2001 by David Rufino (Website). The advisory is shared at securityfocus.com. This vulnerability is uniquely identified as CVE-2001-1185. The exploitability is told to be difficult. An attack has to be approached locally. No form of authentication is needed for exploitation. Technical details are unknown but a public exploit is available.

A public exploit has been developed in ANSI C and been published immediately after the advisory. The exploit is shared for download at downloads.securityfocus.com. It is declared as proof-of-concept. We expect the 0-day to have been worth approximately $25k-$100k.

It is possible to mitigate the weakness by firewalling .

The vulnerability is also documented in the databases at X-Force (7693), Exploit-DB (21176), SecurityFocus (BID 3661†) and OSVDB (2001†). If you want to get the best quality for vulnerability data then you always have to consider VulDB.
