    CVE-2026-22184 (GCVE-0-2026-22184)

    Vulnerability from nvd – Published: 2026-01-07 20:25 – Updated: 2026-06-30 12:06 Disputed
    VLAI
    Title
    zlib <= 1.3.1.2 untgz Global Buffer Overflow in TGZfname()
    Summary
    zlib versions up to and including 1.3.1.2 include a global buffer overflow in the untgz utility located under contrib/untgz. The vulnerability is limited to the standalone demonstration utility and does not affect the core zlib compression library. The flaw occurs when a user executes the untgz command with an excessively long archive name supplied via the command line, leading to an out-of-bounds write in a fixed-size global buffer.
