Discussion
IAXClient Multiple Truncated IAX Frames Remote Buffer Overflow Vulnerabilities
The IAXClient library is prone to multiple remote buffer-overflow vulnerabilities because it fails to properly bounds-check user-supplied input before copying it to insufficiently sized memory buffers.
These issues allow remote attackers to execute arbitrary machine code in the context of applications that use the affected library to process IAX network datagrams.
The following packages are known to use a vulnerable version of the library:
- IDE FISK, versions 1.35 and prior
- IaxComm, versions prior to 1.2.0
- KIAX, versions 0.8.5 and prior
- LoudHush, versions 1.3.6 and prior
Other packages may also use the affected library.
