The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 7-Zip is a file archiver with a high compression ratio. Versions 26.00 and prior contain a heap buffer     overflow vulnerability caused by an under-allocation in the NTFS compressed stream buffer (GetCuSize shift     UB), potentially allowing attackers to cause arbitrary code execution or application crashes.
    CInStream::GetCuSize() in the NTFS handler computes the compression-unit buffer size as (UInt32)1 <<     (BlockSizeLog + CompressionUnit), and a crafted image with ClusterSizeLog >= 28 and CompressionUnit == 4     drives the exponent to 32, which is undefined behavior and collapses on x86/x64 so _inBuf is allocated as     1 byte. ReadStream_FALSE then writes up to 256 MB of attacker-controlled data into that 1-byte buffer in     64 KB iterations, and because the CInStream object sits only 304 bytes after _inBuf, its vtable pointer is     overwritten and the next dispatched call achieves a vtable hijack. On 32-bit builds the overflow is     unconditionally reached; on 64-bit it requires the parallel 8 GB _outBuf allocation to succeed, otherwise     failing closed to denial of service. The NTFS handler is enabled by default in stock 7z.dll and, via     signature-based fallback matching NTFS  at offset 3, will open a crafted image regardless of file     extension during extraction or testing. Version 26.01 fixes the issue. (CVE-2026-48095)

Note that Nessus relies on the presence of the package as reported by the vendor.
