CVE-2026-120756

HDF5 through 2.2.0 contains a heap buffer over-read vulnerability in H5Ochunkdeserialize in src/H5Ocache.c. When decoding object header messages, the declared message size is checked against the end of the chunk image before the remainder of the message header flags, and for version 2 object...

CVE-2026-120757

HDF5 through 2.2.0 contains a heap buffer over-read vulnerability in H5Lexterntraverse in src/H5Lexternal.c, the default traversal callback for external links. The callback locates the target file name and object path within the link’s user data using strlen without validating the buffer against...

SUSE CVE-2026-121397

FreeRDP before 3.32.2 contains a heap buffer over-read vulnerability in savepngtobuffer that allows malicious RDP servers to leak client memory by sending 16 bpp DIB clipboard data. Attackers can offer a CFDIB BIBITFIELDS image that, when converted to PNG for a local application, embeds client he...

CVE-2026-121397

A flaw was found in FreeRDP. A malicious Remote Desktop Protocol RDP server can cause an information disclosure by sending crafted clipboard image data to a connected client. When the client converts the image into Portable Network Graphics PNG format, a heap buffer over-read occurs, embedding...

CVE-2026-120757

A flaw was found in HDF5. When traversing external links, the library fails to validate the length of user-supplied link data, resulting in a heap buffer over-read. By convincing a user or application to open a specially crafted HDF5 file containing a malformed external link, an attacker can caus...

CVE-2026-120756

A flaw was found in hdf5. When parsing object header messages, insufficient boundary checks can allow an attacker to trigger a heap buffer over-read by convincing a user or application to open a specially crafted file. Successful exploitation could cause the application to crash, resulting in a...
