EUVDB-ID: #VU33120

Risk: Medium

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2011-2911

CWE-ID: CWE-122 - Heap-based Buffer Overflow

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in Integer overflow in the CSoundFile::ReadWav function in src/load_wav.cpp in libmodplug before 0.8.8.4. A remote attacker can use a crafted WAV file to trigger heap-based buffer overflow and execute arbitrary code on the target system.
