CVE-2018-10538: Debian Linux

Medium severity, CVSS 5.5. EPSS: 1.7% chance of exploitation in the next 30 days.

An issue was discovered in WavPack 5.1.0 and earlier for WAV input. Out-of-bounds writes can occur because ParseRiffHeaderConfig in riff.c does not validate the sizes of unknown chunks before attempting memory allocation, related to a lack of integer-overflow protection within a bytes_to_copy calculation and subsequent malloc call, leading to insufficient memory allocation.

Affected products

• Debian Debian Linux: version 8.0 only; version 9.0 only
• Wavpack Wavpack: up to and including 5.1.0
