Detail
| Several security related problems have been found in the xtell package, a simple messaging client and server. In detail, these problems contain several buffer overflows, a problem in connection with symbolic links, unauthorized directory traversal when the path contains "..". These problems could lead into an attacker being able to execute arbitrary code on the server machine. The server runs with nobody privileges by default, so this would be the account to be exploited. They have been corrected by backporting changes from a newer upstream version by the Debian maintainer for xtell. These problems are fixed in version 1.91.1 in the stable distribution of Debian and in version 2.7 for the testing and unstable distribution of Debian. We recommend that you upgrade your xtell packages immediately. wget url will fetch the file for you dpkg -i file.deb will install the referenced file. If you are using the apt-get package manager, use the line for sources.list as given below: apt-get update will update the internal database apt-get upgrade will install corrected packages You may use an automated update by adding the resources from the footer to the proper configuration.

| 9049 | xtell TTY Argument Arbitrary File Access |
| 5838 | Xtell Port 4224 Data Overflow A remote overflow exists in Xtell. The Xtelld daemon fails to perform proper bounds checking resulting in a buffer overflow. With a specially crafted request to port 4224, a remote attacker can cause arbitrary code execution resulting in a loss of integrity. |
| 5837 | Xtell Long AUTH String Overflow A remote overflow exists in Xtell. The program fails to perform proper length checking of the AUTH string obtained from the AUTH service resulting in a buffer overflow. With a specially crafted request, a remote attacker can cause arbitrary code execution resulting in a loss of integrity. |
| 5836 | Xtell Long DNS Name Overflow A remote overflow exists in Xtell. The Xtelld daemon fails to perform proper bounds checking resulting in a buffer overflow. With a specially crafted request, a remote attacker can cause arbitrary code execution with the UID of the Xtell daemon resulting in a loss of integrity. |
