Authored by Ulf Harnhammar | Site secunia.com

Secunia Research has discovered a vulnerability in GNU Enscript, which can be exploited by malicious people to compromise a vulnerable system. The vulnerability is caused due to a boundary error within the "read_special_escape()" function in src/psgen.c. This can be exploited to cause a stack-based buffer overflow by tricking the user into converting a malicious file. Successful exploitation allows execution of arbitrary code, but requires that special escapes processing is enabled with the "-e" option. GNU Enscript versions 1.6.1 and 1.6.4 beta are vulnerable.

Secunia Research has discovered a vulnerability in Evolution, which can be exploited by malicious people to potentially compromise a vulnerable system. A format string error in the "write_html()" function in calendar/gui/ e-cal-component-memo-preview.c when displaying a memo's categories can potentially be exploited to execute arbitrary code via a specially crafted shared memo containing format specifiers. Evolution version 2.8.2.1 is affected. Other versions may also be affected.

kses-0.2.2.tar.gz

Authored by Ulf Harnhammar, Richard R. Vasquez, Simon Cornelius P. Umacob | Site sourceforge.net

kses is an HTML/XHTML filter written in PHP. It removes all unwanted HTML elements and attributes, no matter how malformed HTML input you give it. It also does several checks on attribute values. kses can be used to avoid Cross-Site Scripting (XSS), Buffer Overflows and Denial of Service attacks, among other things.

Changes: The 0.2.2 release adds a second object-oriented kses version for PHP 5, the use of isset() avoids PHP notice warnings, the chr(173) handling is changed to help Asian users, and the handling of closing HTML elements is improved, among other changes.

Authored by Ulf Harnhammar | Site secunia.com

Alexandria versions 2.5 and 2.0, the open-source project management system used by Sourceforge, has multiple vulnerabilities in its PHP scripts. In the upload scripts there is a lack of input validation that allows an attacker to remotely retrieve any files off of the system, such as /etc/passwd. Other vulnerabilities including the sendmessage.php script allowing spammers to make use of it to mask real source identities and various cross site scripting problems exist as well.

Hypermail 2, a popular tool that converts mails into html, has two buffer overflows. One exists in the hypermail program itself and another is in the CGI program mail. The overflow in the main program can be overflowed by sending an email while the CGI program can be overflowed by a DNS server being populated with faulty information. Versions affected: 2.1.3, 2.1.4, 2.1.5, possibly others. 2.1.6 is not affected.

fopen(), file() and other functions in PHP have a vulnerability that makes it possible to add extra HTTP headers to HTTP queries. Attackers may use it to escape certain restrictions, like what host to access on a web server. In some cases, this vulnerability even opens up for arbitrary net connections, turning some PHP scripts into proxies and open mail relays.
