BugTraq ID: 11221
Remote: Yes
Date Published: Sep 20 2004
Relevant URL: http://www.securityfocus.com/bid/11221
Summary:
Tutos is reported prone to multiple remote input validation 
vulnerabilities.  These issues exist due to insufficient sanitization of

and SQL injection attacks.

These issue reportedly affect Tutos 1.1.2004-04-14.

3. FreeRADIUS Access-Request Denial Of Service Vulnerability
BugTraq ID: 11222
Remote: Yes
Date Published: Sep 20 2004
Relevant URL: http://www.securityfocus.com/bid/11222
Summary:
Reportedly FreeRADIUS is affected by a remote denial of service 
vulnerability.  This issue is due to a failure of the application to handle 
malformed packets.

An attacker may leverage this issue to cause the affected server to 
crash, denying service to legitimate users.

4. Getmail Local Symbolic Link Vulnerability
BugTraq ID: 11224
Remote: No
Date Published: Sep 20 2004
Relevant URL: http://www.securityfocus.com/bid/11224
Summary:
Reportedly getmail is affected by a local symbolic link vulnerability. 
This issue is due to a failure of the application to validate files 
prior to writing to them.

An attacker may leverage this issue to cause arbitrary files to be 
written to with the privileges of a user that sends messages to an 
attacker-controlled file.  This may facilitate privilege escalation or 
destruction of data.

5. Jabber Studio JabberD Remote Denial Of Service Vulnerability
BugTraq ID: 11231
Remote: Yes
Date Published: Sep 21 2004
Relevant URL: http://www.securityfocus.com/bid/11231
Summary:
Jabber Studio jabberd is reportedly affected by a remote denial of 
service vulnerability.  This issue is due to a failure of the application

crash, denying service to legitimate users.

6. YaBB 1 Gold Multiple Input Validation Vulnerabilities
BugTraq ID: 11235
Remote: Yes
Date Published: Sep 22 2004
Relevant URL: http://www.securityfocus.com/bid/11235
Summary:
YaBB 1 Gold is affected by multiple input validation vulnerabilities.  
These issues are due to a failure of the application to properly 
sanitize user-supplied input.

An attacker may leverage a cross-site scripting issue to execute 
arbitrary HTML and script code in the browser of an unsuspecting user in the 
context of the vulnerable site.  This may facilitate the theft of 
cookie-based authentication credentials as well as other attacks.

An attacker may exploit a HTTP response splitting issue to manipulate 
or misrepresent pages in the context of the vulnerable site, potentially 
facilitating phishing attacks.

vulnerability.  This issue presents itself due to an unspecified error in 
the merging of the 'Satisfy' directive.  As a result, a remote attacker 
may bypass access controls and gain unauthorized access to restricted 
resources.

It is reported that this issue only affects Apache 2.0.51.

Due to a lack of details, further information is not available at the

reportedly possible to disclose the existence of files that are 
inaccessible to users. Under certain circumstances it may also be possible to 
disclose commit log messages, or even the contents of files that are 
configured to be inaccessible to users.

to gain administrative access to the web application.

The second issue is a source code disclosure vulnerability. This 
vulnerability allows attackers to retrieve the contents of potentially 
sensitive script files. This may aid them in further attacks.

The third issue is a buffer overflow vulnerability allowing remote 
attackers to reportedly crash affected servers.

Versions 3.0, 3.1, and 4.0 are reportedly affected by these 
vulnerabilities.

attacker to gain unauthorized access to a vulnerable computer.

Reportedly, this issue affects Zinf version 2.2.1 for Windows.  Zinf 
version 2.2.5 for Linux is reportedly fixed, however, this is not 
confirmed at the moment.
