CVE-2026-64200

Out Of Bounds Read during string conversion when parsing a .DSB file in DASYLab

There is an out-of-bounds read vulnerability in DASYLab due to improper validation of user-supplied data.   This results in a read a past the end of an allocated heap buffer during string conversion.  Successful exploitation requires an attacker to get a user to open a specially crafted .DSB file.  This issue affects all versions before 2026.0.0.

CVE-2026-85234

Tftp: tftp-hpa: denial of service due to out-of-bounds read/write in remap engine

A flaw was found in tftp-hpa. When the `in.tftpd` remap engine processes an inverse remap rule that also aborts with a non-empty custom error message, it can pass invalid match offsets to the `genmatchstring()` function. This leads to out-of-bounds read/write operations. A remote, unauthenticated attacker can exploit this vulnerability by sending a specially crafted request, causing the daemon to crash and resulting in a denial of service.

Libsoup: libsoup: heap buffer overflow during outgoing permessage-deflate buffer growth

A flaw was found in libsoup. When the permessage-deflate WebSocket extension compresses a very large outgoing message, truncated size calculations used for GByteArray growth could wrap, causing zlib to write past the allocated buffer and resulting in a heap buffer overflow.

CVE-2026-102559

Libsoup: libsoup: heap buffer overflow during websocket client-frame masking

A flaw was found in libsoup. When constructing a masked WebSocket client frame for a very large outgoing payload, size values passed to GByteArray allocation APIs could be truncated while the masking routine still used the full length, causing a heap buffer overflow.

CVE-2026-102558

Libsoup: libsoup: heap buffer overflow during websocket receive-buffer growth

A flaw was found in libsoup. When max-incoming-payload-size is unlimited (0), SoupWebsocketConnection could grow its incoming GByteArray based on an attacker-controlled frame length until the length wrapped, causing a heap buffer overflow while reading frame data.
