The following package needs to be updated: gallery

Sverre H. Huseby discovered a vulnerability in Adobe Acrobat and Adobe Reader. Under certain circumstances, using XML scripts it is possible to discover the existence of local files.

The following package needs to be updated: isc-dhcp3

An NGSSoftware Insight Security Research Advisory reports :

Two vulnerabilities have been discovered in RealPlayer which may potentially be leveraged to allow remote code execution, or may used in combination with the Real Metadata Package File Deletion vulnerability to reliably delete files from a users system.

When a user is granted access to a database with a name containing an underscore and the underscore is not escaped then that user might also be able to access other, similarly named, databases on the affected system.

The problem is that the underscore is seen as a wildcard by MySQL and therefore it is possible that an admin might accidentally GRANT a user access to multiple databases.

The eqn2graph and pic2graph scripts in groff 1.18.1 allow local users to overwrite arbitrary files via a symlink attack on temporary files.

A Debian Security Advisory reports :

Ulf Harnhammar from the Debian Security Audit Project discovered a buffer overflow in axel, a light download accelerator. When reading remote input the program did not check if a part of the input can overflow a buffer and maybe trigger the execution of arbitrary code.

The following package needs to be updated: cvstrac

The remote host is running a version of FreeBSD which contains a flaw in the sendfile() API.

There is an error in the sendfile() API which may allow a local user to disclose parts of the contents of the kernel memory.

The remote host is running a version of FreeBSD which contains a flaw in the 'fetch' utility.

'fetch' is a command-line tool used to retrieve data at a given URL. It is used (among others) by the FreeBSD port collection.

There is an integer overflow condition in the processing of HTTP headers which may result in a buffer overflow.

An attacker may exploit this flaw to execute arbitrary commands on the remote host. To exploit this flaw, an attacker would need to lure a victim on the remote host into downloading a URL from a malicious web server using this utility.

The remote host has the following package installed :
	0.8.0 <= freeradius < 1.0.1


The remote version of this software is vulnerable to a flaw which may allow an attacker to disable this service remotely.

The remote host is running a version of FreeBSD which contains a flaw in the syscons console driver.

There are boundary errors in the CONS_SCRSHOT ioctls that may allow a local attacker to read portions of the kernel memory, which may contain sensitive information.

Marcus Meissner discovered that ImageMagick's BMP decoder would crash when loading the test BMP file created by Chris Evans for testing the previous Qt vulnerability.

The following package needs to be updated: nss

According to the SpamAssassin 2.64 release announcement :

Security fix prevents a denial of service attack open to certain malformed messages; this DoS affects all SpamAssassin 2.5x and 2.6x versions to date.

The issue appears to be triggered by overly long message headers.

Qt contains several vulnerabilities related to image loading, including possible crashes when loading corrupt GIF, BMP, or JPEG images. Most seriously, Chris Evans reports that the BMP crash is actually due to a heap buffer overflow. It is believed that an attacker may be able to construct a BMP image that could cause a Qt-using application to execute arbitrary code when it is loaded.

According to a Debian Security Advisory :

Andres Salomon noticed a problem in the CGI session management of Ruby, an object-oriented scripting language. CGI::Session's FileStore (and presumably PStore [...]) implementations store session information insecurely. They simply create files, ignoring permission issues. This can lead an attacker who has also shell access to the webserver to take over a session.

An iDEFENSE security advisory reports :

Remote exploitation of an input validation error in the uudecoding feature of Adobe Acrobat Reader (Unix) 5.0 allows an attacker to execute arbitrary code.

The Unix and Linux versions of Adobe Acrobat Reader 5.0 automatically attempt to convert uuencoded documents back into their original format. The vulnerability specifically exists in the failure of Acrobat Reader to check for the backtick shell metacharacter in the filename before executing a command with a shell. This allows a maliciously constructed filename to execute arbitrary programs.

SSLtelnet contains a format string vulnerability that could allow remote code execution and privilege escalation.

The remote host is running a version of the FreeBSD kernel which may be contains a programming error in the shmat(2) system call which can let a local attacker to gain read or write access to a portion of the kernel memory which in turn might be used to elevate his privileges or gain access to sensitive information.

The remote host is running a version of FreeBSD 5.2 older than FreeBSD 5.2.1-p4

There is a programming error in the version of this kernel which may allow a local attacker to read portions of the kernel memory or to cause a system panic by misusing the setsockopt() system call on IPv6 sockets.

The remote host is running a version of the FreeBSD kernel which may be vulnerable to a remote denial of service attack when processing many out of sequence TCP packets.

A remotely exploitable heap buffer overflow vulnerability was found in MPlayer's URL decoding code. If an attacker can cause MPlayer to visit a specially crafted URL, arbitrary code execution with the privileges of the user running MPlayer may occur. A `visit' might be caused by social engineering, or a malicious web server could use HTTP redirects which MPlayer would then process.

The remote host is running a version of FreeBSD which contains a bug in the mksnap_ffs(8) utility which may reset file flags on the remote file system, thus resetting the type of access control that were assigned to a file.

The remote host is running a version of the FreeBSD kernel which contains a programming error in the way it handles some Linux system calls, which may be exploited by an attacker to gain super-user privileges on the remote host, or to crash it.

The remote host is running a version of the FreeBSD kernel which contains a bug which may allow a jailed process to attach to another jail.

An attacker compromised a jailed process on the remote host could exploit this flaw to switch to other jails on the system.

The remote host is running a version of the FreeBSD kernel which contains a bug which may allow a jailed process to modify the host routing tables of the whole system.

The remote host is running a version of FreeBSD which contains a heap overflow in the cvs pserver code. This flaw may be used by an attacker to execute arbitrary code on the remote host, provided that it's running a cvs pserver.

The remote host is running a version of FreeBSD which contains a programming error in the msync(2) system call which may let a local user with read access to a given file to forbid any change to this file to be written to disk.
