Vulnerability Spotlight: Three vulnerabilities in HDF5 file format could lead to remote code execution
Summary: Cisco Talos discovered three vulnerabilities in the libhdf5 gif2h5 tool, which converts GIF files to the HDF5 format, that could allow an attacker to execute remote code on a targeted device. TALOS-2022-1485 (CVE-2022-25972) and TALOS-2022-1486 (CVE-2022-25942) are out-of-bounds write vulnerabilities that trigger a specific crash, while TALOS-2022-1487 (CVE-2022-26061) is a heap-based buffer overflow, and Talos disclosed them without an official fix from HDF5 under its 90-day deadline.
Why it matters: Talos confirmed version 1.10.4 of HDF5 Group libhdf5 could be exploited, and the disclosure went out with no official fix available, so anyone running that library has to rely on the listed Snort rules (59296, 59297, 59300, 59301, 59303, 59304) until a patch exists.
