BladeEnc myFseek() code execution
| bladeenc-myfseek-code-execution (11227) |  Medium Risk |
Description:
BladeEnc could allow a remote attacker to execute arbitrary code on the system, caused by a vulnerability in the myFseek() function. The myFseek() function fails to properly validate the "offset" variable. A remote attacker could exploit this vulnerability by creating a malicious audio file, and sending it to a victim as an email attachment or hosting it on a Web site, which would cause arbitrary code to be executed on the victim's system when encoded using the BladeEnc encoder.
Platforms Affected:
- Gentoo, Linux
- Tord Jansson, BladeEnc 0.94.2 and prior
Remedy:
For Gentoo Linux:
Upgrade to the latest version of bladeenc (0.94.2-r1 and later), as listed in Gentoo Linux Security Announcement 200302-04. See References.
For other distributions: Contact your vendor for upgrade or patch information..
