UNKNOWN Summary
Integer overflow in the qt_error parse_trak_atom function in demuxers/demux_qt.c in xine-lib 1.1.16.2 and earlier allows remote attackers to execute arbitrary code via a Quicktime movie file with a large count value in an STTS atom, which triggers a heap-based buffer overflow.

Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Buffer Overflow via Environment Variables This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
- Overflow Buffers Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
- Client-side Injection-induced Buffer Overflow This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
- Filter Failure through Buffer Overflow In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
- MIME Conversion An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

NASL family Mandriva Local Security Checks NASL id MANDRIVA_MDVSA-2009-319.NASL description Vulnerabilities have been discovered and corrected in xine-lib : Failure on Ogg files manipulation can lead remote attackers to cause a denial of service by using crafted files (CVE-2008-3231). Failure on manipulation of either MNG or Real or MOD files can lead remote attackers to cause a denial of service by using crafted files (CVE: CVE-2008-5233). Heap-based overflow allows remote attackers to execute arbitrary code by using Quicktime media files holding crafted metadata (CVE-2008-5234). Heap-based overflow allows remote attackers to execute arbitrary code by using either crafted Matroska or Real media files (CVE-2008-5236). Failure on manipulation of either MNG or Quicktime files can lead remote attackers to cause a denial of service by using crafted files (CVE-2008-5237). Multiple heap-based overflow on input plugins (http, net, smb, dvd, dvb, rtsp, rtp, pvr, pnm, file, gnome_vfs, mms) allow attackers to execute arbitrary code by handling that input channels. Further this problem can even lead attackers to cause denial of service (CVE-2008-5239). Heap-based overflow allows attackers to execute arbitrary code by using crafted Matroska media files (MATROSKA_ID_TR_CODECPRIVATE track entry element). Further a failure on handling of Real media files (CONT_TAG header) can lead to a denial of service attack (CVE-2008-5240). Integer underflow allows remote attackers to cause denial of service by using Quicktime media files (CVE-2008-5241). Failure on manipulation of Real media files can lead remote attackers to cause a denial of service by indexing an allocated buffer with a certain input value in a crafted file (CVE-2008-5243). Vulnerabilities of unknown impact - possibly buffer overflow - caused by a condition of video frame preallocation before ascertaining the required length in V4L video input plugin (CVE-2008-5245). Heap-based overflow allows remote attackers to execute arbitrary code by using crafted media files. This vulnerability is in the manipulation of ID3 audio file data tagging mainly used in MP3 file formats (CVE-2008-5246). Integer overflow in the qt_error parse_trak_atom function in demuxers/demux_qt.c in xine-lib 1.1.16.2 and earlier allows remote attackers to execute arbitrary code via a Quicktime movie file with a large count value in an STTS atom, which triggers a heap-based buffer overflow (CVE-2009-1274) Integer overflow in the 4xm demuxer (demuxers/demux_4xm.c) in xine-lib 1.1.16.1 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a 4X movie file with a large current_track value, a similar issue to CVE-2009-0385 (CVE-2009-0698) Packages for 2008.0 are provided for Corporate Desktop 2008.0 customers This update fixes these issues. last seen 2020-06-01 modified 2020-06-02 plugin id 43022 published 2009-12-07 reporter This script is Copyright (C) 2009-2019 Tenable Network Security, Inc. source https://www.tenable.com/plugins/nessus/43022 title Mandriva Linux Security Advisory : xine-lib (MDVSA-2009:319) NASL family SuSE Local Security Checks NASL id SUSE_XINE-DEVEL-6229.NASL description This update of xine-lib fixes an integer overflow in the qt_error parse_trak_atom() function in that leads to a heap-based overflow and allows remote attackers to execute arbitrary code via a malformed Quicktime movie file.
