Integer overflow in the LZ4 algorithm implementation, as used in Yann Collet LZ4 before r118 and in the lz4_uncompress function in lib/lz4/lz4_decompress.c in the Linux kernel before 3.15.2, on 32-bit platforms might allow context-dependent attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via a crafted Literal Run that would be improperly handled by programs not complying with an API limitation, a different vulnerability than CVE-2014-4715.

Security readout for executives and security teams

CVE-2014-4611 is an old LZ4 decompression flaw affecting 32-bit use cases. A crafted compressed input could corrupt memory, most clearly causing denial of service. Business urgency depends on whether legacy 32-bit Linux kernels or bundled pre-r118 LZ4 code still process untrusted compressed data. Exposure is most plausible in legacy 32-bit systems, old Linux kernels before 3.15.2, or software embedding LZ4 before r118 and decompressing attacker-supplied data. Current exposure cannot be inferred from the bundle alone. Treat as a legacy exposure check, not an emergency, unless vulnerable 32-bit decompression is still reachable by untrusted input. Prioritize inventory and patch verification for older Linux and bundled compression libraries. Mitigation focus: Inventory legacy 32-bit systems and embedded LZ4 copies.; Upgrade Yann Collet LZ4 to r118 or later where applicable.; Upgrade Linux kernels to 3.15.2 or vendor-fixed releases where applicable..
