CVE-2017-11126: MPG123

Medium severity, CVSS 5.5. EPSS: 1.4% chance of exploitation in the next 30 days.

The III_i_stereo function in libmpg123/layer3.c in mpg123 through 1.25.1 allows remote attackers to cause a denial of service (buffer over-read and application crash) via a crafted audio file that is mishandled in the code for the "block_type != 2" case, a similar issue to CVE-2017-9870.
