Description:
David Thiel has reported some vulnerabilities in libvorbis, which can be exploited by malicious people to cause a DoS (Denial of Service) and potentially compromise an application using the library.
1) A boundary error exists in the way the "_01inverse()" function in res.c processes "blocksize_0" and "blocksize_1" values, which can be exploited to cause a heap overwrite.
2) A boundary error exists in the way the "vorbis_info_clear()" function in info.c processes invalid mapping types, which can be exploited to trigger a call to a value outside the dispatch table.
3) Invalid "blocksize" values passed to the "vorbis_dsp_clear()" function in block.c result in an invalid memory access, which can be exploited to cause a DoS.
Note: Other errors, where some may have a security impact, were also reported.
The vulnerabilities are reported in version 1.1.2. Prior versions may also be affected.
