Tenshi Log Monitoring Program 0.13
Posted Jul 14, 2011
Authored by Andrea Barisani | Site dev.inversepath.com

Tenshi is a log monitoring program, designed to watch a log file for lines matching user defined regular expression and report on the matches. The regular expressions are assigned to queues which have an alert interval and a list of mail recipients. Queues can be set to send a notification as soon as there is a log line assigned to it, or to send periodic reports.

Changes: Added threshold feature for discarding logs with count below specified value. Fixed broken queue flushing on exit. Various other improvements.

The libavcodec library, an open source video encoding/decoding library part of the FFmpeg project, suffers from an arbitrary offset dereference vulnerability. The vulnerability affects the flic file format parser, insufficient restrictions on a writable buffer can be exploited to execute arbitrary code via the heap memory. A specific flic file can be crafted to trigger the vulnerability. Versions 0.6 and below are affected.

The libtiff image library tools suffer from integer overflows which may lead to a potentially exploitable heap overflow and result in arbitrary code execution. The libtiff package ships a library, for reading and writing TIFF, as well as a small collection of tools for manipulating TIFF images. The cvt_whole_image function used in the tiff2rgba tool and the tiffcvt function used in the rgb2ycbcr tool do not properly validate the width and height of the image. Specific TIFF images with large width and height can be crafted to trigger the vulnerability.

Dillo, an open source graphical web browser, suffers from an integer overflow which may lead to a potentially exploitable heap overflow and result in arbitrary code execution. The vulnerability is triggered by HTML pages with embedded PNG images, the Png_datainfo_callback function does not properly validate the width and height of the image. Specific PNG images with large width and height can be crafted to trigger the vulnerability. Versions 2.1 and below are affected.

FCKeditor, a web based open source HTML text editor, suffers from a remote file upload vulnerability. The input of several connector modules is not properly verified before being used, this leads to exposure of the contents of arbitrary directories on the server filesystem and allows file uploading to arbitrary locations. The affected code is remotely exposed before authentication. An attacker can exploit this vulnerability to install remote shells on the victim server among other things, it should be noted that this vulnerability is being actively exploited in the wild. Versions 2.6.4 and below are affected.

CamlImages versions 2.2 and below suffer from several integer overflows which may lead to a potentially exploitable heap overflow and result in arbitrary code execution. The vulnerability is triggered by PNG image parsing, the read_png_file and read_png_file_as_rgb24 functions do not properly validate the width and height of the image. Specific PNG images with large width and height can be crafted to trigger the vulnerability.

The MPlayer multimedia player suffers from a vulnerability which could result in arbitrary code execution and at the least, in unexpected process termination. Three integer underflows located in the Real demuxer code can be used to exploit a heap overflow, a specific video file can be crafted in order to make the stream_read function reading or writing arbitrary amounts of memory. Versions 1.0 RC2 and below are affected.

Authored by Andrea Barisani | Site dev.inversepath.com

Tenshi is a log monitoring program, designed to watch a log file for lines matching user defined regular expression and report on the matches. The regular expressions are assigned to queues which have an alert interval and a list of mail recipients. Queues can be set to send a notification as soon as there is a log line assigned to it, or to send periodic reports.

Changes: Multiple bug fixes and some improvements.
