Stack-based buffer overflow in the CSmil1Parser::testAttributeFailed function in smlparse.cpp for RealNetworks RealPlayer 10.5 (6.0.12.1056 and earlier), 10, 8, and RealOne Player V2 and V1 allows remote attackers to execute arbitrary code via a .SMIL file with a large system-screen-size value.

Updated HelixPlayer packages that fixes two buffer overflow issues are now available.

This update has been rated as having critical security impact by the Red Hat Security Response Team.

A stack based buffer overflow bug was found in HelixPlayer's Synchronized Multimedia Integration Language (SMIL) file processor. An attacker could create a specially crafted SMIL file which would execute arbitrary code when opened by a user. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2005-0455 to this issue.

A buffer overflow bug was found in the way HelixPlayer decodes WAV files. An attacker could create a specially crafted WAV file which could execute arbitrary code when opened by a user. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2005-0611 to this issue.

All users of HelixPlayer are advised to upgrade to this updated package, which contains HelixPlayer 1.0.3 which is not vulnerable to these issues.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Updated realplayer packages that fix a number of security issues are now available for Red Hat Enterprise Linux 3 Extras.

This update has been rated as having important security impact by the Red Hat Security Response Team.

The realplayer package contains RealPlayer, a media format player.

A number of security issues have been discovered in RealPlayer 8 of which a subset are believed to affect the Linux version as shipped with Red Hat Enterprise Linux 3 Extras. RealPlayer 8 is no longer supported by RealNetworks.

Users of RealPlayer are advised to upgrade to this erratum package which contains RealPlayer 10.

The remote host is missing the patch for the advisory SUSE-SA:2005:014 (RealPlayer).


Two security problems were found in the media player RealPlayer:

- CVE-2005-0455: A buffer overflow in the handling of .smil files.
- CVE-2005-0611: A buffer overflow in the handling of .wav files.

Both buffer overflows can be exploited remotely by providing URLs opened by RealPlayer.

A buffer overflow bug was found in the way RealPlayer decodes WAV sound files. An attacker could create a specially crafted WAV file which could execute arbitrary code when opened by a user. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2005-0611 to this issue.

All users of RealPlayer are advised to upgrade to this updated package, which contains RealPlayer version 10.0.3 and is not vulnerable to these issues.

The remote host has the RealPlayer software installed.

There are several flaws in the remote version of this software that might allow
an attacker to execute arbitrary code and delete arbitrary files on the remote
host.

To exploit these flaws, an attacker would need to send a malformed SMIL or
WAV file to a user on the remote host and wait for the file to be opened in RealPlayer. 

According to its build number, the installed version of RealPlayer / RealOne Player / RealPlayer Enterprise for Windows might allow an attacker to execute arbitrary code and delete arbitrary files on the remote host. 

To exploit these flaws, an attacker would send a malformed SMIL or WAV file to a user on the remote host and wait for him to open it.
