II. LINUX VULNERABILITY SUMMARY
-------------------------------
1. GV Postscript and PDF Viewer Multiple Remote Buffer Overflow...
BugTraq ID: 10944
Remote: Yes
Date Published: Aug 14 2004
Relevant URL: http://www.securityfocus.com/bid/10944
Summary:
gv is reported prone to multiple remote buffer overflow
vulnerabilities. These issues exist due to insufficient checking performed by the
application on file headers for PostScript and PDF documents.
These vulnerabilities exist in the 'psscan' function of the 'ps.c'
file. The vulnerabilities include multiple stack and heap based buffer
overflows. A number of the stack overflows have been specified, however,
there are also a number of unspecified heap overflows.
Successful exploitation of these issues may result in an attacker
executing arbitrary code on a vulnerable computer to gain unauthorized
access. This would occur in the context of the vulnerable application.
It should be noted that applications such as Web browsers may use the
software as an automatic handler for PostScript and PDF files.
2. Gentoo Linux Tomcat EBuild Insecure Install Permissions Vuln...
BugTraq ID: 10951
Remote: No
Date Published: Aug 16 2004
Relevant URL: http://www.securityfocus.com/bid/10951
Summary:
The Gentoo Linux Tomcat eBuild is reported prone to an insecure default
install permission vulnerability. It is reported that certain Tomcat
scripts are installed with permissions that allow members of the tomcat
group to write to the file.
A local attacker that is a member of the Tomcat group may exploit this
condition to escalate privileges.
3. KDE Mcoputils Insecure Temporary File Creation Vulnerability
BugTraq ID: 10952
Remote: No
Date Published: Aug 16 2004
Relevant URL: http://www.securityfocus.com/bid/10952
Summary:
KDEs mcoputils is reported to contain an insecure temporary file
creation vulnerability. The result of this is that temporary files created
by the application may use predictable filenames.
A local attacker may also possibly exploit this vulnerability to
execute symbolic link file overwrite attacks. This may allow an attacker to
overwrite arbitrary files with the privileges of the targeted user.
Privilege escalation may also be possible using this method of attack.
4. PScript PForum User Profile HTML Injection Vulnerability
BugTraq ID: 10954
Remote: Yes
Date Published: Aug 16 2004
Relevant URL: http://www.securityfocus.com/bid/10954
Summary:
PScript PForum is reported prone to a HTML injection vulnerability. The
vulnerability presents itself due to a lack of sufficient sanitization
performed on data submitted through input fields of the PForum user
profile form.
This could be exploited to steal cookie-based authentication
credentials. It is also possible to use this type of vulnerability as an attack
vector to exploit latent browser security flaws.
5. SpamAssassin Malformed Email Remote Denial Of Service Vulner...
BugTraq ID: 10957
Remote: Yes
Date Published: Aug 16 2004
Relevant URL: http://www.securityfocus.com/bid/10957
Summary:
SpamAssassin is reported prone to a remote denial of service
vulnerability. Full details regarding this vulnerability are not known.
A remote attacker may potentially exploit this vulnerability to deny
service to a target SpamAssassin service.
SpamAssassin versions prior to 2.64 are reported vulnerable to this
issue.
This BID will be updated as further details regarding this
vulnerability are announced.
6. RXVT-Unicode Open File Descriptor Leakage Vulnerability
BugTraq ID: 10959
Remote: No
Date Published: Aug 16 2004
Relevant URL: http://www.securityfocus.com/bid/10959
Summary:
It is reported that RXVT-Unicode fails to properly close file
descriptors when spawning new child terminal windows.
The child process could then potentially gain access to possibly
sensitive information from the contents of the open file descriptors.
Depending on the mode of the original file, and the privileges of the user
that opened it, processes in the child window may exploit this
vulnerability to take control of the parent process. Other attacks may also be
possible.
An attacker requires local access to the RXVT-Unicode process window to
exploit this vulnerability.
Versions prior to 3.6 are reported vulnerable to this issue.
7. RaXnet Cacti Auth_Login.PHP SQL Injection Vulnerability
BugTraq ID: 10960
Remote: Yes
Date Published: Aug 16 2004
Relevant URL: http://www.securityfocus.com/bid/10960
Summary:
RaXnet Cacti is reportedly affected by a remote SQL injection
vulnerability. This issue occurs in the auth_login.php script due to a failure
of the application to properly sanitize user-supplied "username" URI
parameter input before using it in an SQL query.
It is demonstrated that an attacker may exploit this vulnerability in
order to bypass the authentication interface used by Cacti.
8. GNU GLibC LD_DEBUG Local Information Disclosure Vulnerabilit...
BugTraq ID: 10963
Remote: No
Date Published: Aug 17 2004
Relevant URL: http://www.securityfocus.com/bid/10963
Summary:
A local vulnerability is reported to exist in glibc, it is reported
that LD_DEBUG is allowed on setuid binaries even though this should not be
allowed. A local attacker may debug a setuid binary and may disclose
sensitive information.
Information harvested in this manner may be employed to aid in further
attacks that are launched against a vulnerable host.
9. GYach Enhanced Multiple Undisclosed Vulnerabilities
BugTraq ID: 10975
Remote: Yes
Date Published: Aug 18 2004
Relevant URL: http://www.securityfocus.com/bid/10975
Summary:
GYach is reported prone to multiple undisclosed vulnerabilities. One of
the flaws reported is a denial of service vulnerability. Few details
are known in regard to the other reported issues.
A remote attacker may exploit these vulnerabilities to deny service to
the vulnerable client, other types of security compromise may also be
possible.
Details regarding these vulnerabilities are not available. This BID
will be updated as further information regarding these vulnerabilities is
announced.
10. Courier-IMAP Remote Format String Vulnerability
BugTraq ID: 10976
Remote: Yes
Date Published: Aug 18 2004
Relevant URL: http://www.securityfocus.com/bid/10976
Summary:
Courier-IMAP is reported to be susceptible to a remote format string
vulnerability. This issue is due to a failure of the application to
properly sanitize user-supplied input before using it as the format
specifier in a formatted printing function.
Successful exploitation of this issue will allow an attacker to execute
arbitrary code on the affected computer with the privileges of the user
that the IMAP daemon runs as. This vulnerability is exploitable prior
to authentication.
Courier-IMAP versions 1.6.0 through to 2.2.1 are reported vulnerable.
Other versions may also be vulnerable.
11. Multiple Qt Image Handling Heap Overflow Vulnerabilities
BugTraq ID: 10977
Remote: Yes
Date Published: Aug 19 2004
Relevant URL: http://www.securityfocus.com/bid/10977
Summary:
Multiple heap overflows have been reported to exist in the Qt QImage
library. These issues may be triggered when handling malformed images of
various types, potentially causing a denial of service in applications
that use the library to render images. Remote code execution is also
possible.
12. MySQL Mysql_real_connect Function Potential Remote Buffer Ov...
BugTraq ID: 10981
Remote: Yes
Date Published: Aug 20 2004
Relevant URL: http://www.securityfocus.com/bid/10981
Summary:
MySQL is prone to a potential remote buffer overflow vulnerability.
This issue occurs due to insufficient boundary checks performed by the
'mysql_real_connect' function.
The 'mysql_real_connect' function does not verify the length of the IP
address returned through a DNS response from a server. Immediate
consequences of an attack may result in a denial of service condition. It
is conjectured that this issue could allow for arbitrary code execution,
however, this has not been confirmed.
It is also reported that the glibc library verifies the length of an IP
address, however, other libraries may obtain the length from a DNS
response packet. Computers using glibc on Linux and BSD platforms may not
be vulnerable to this issue.
