re2: Out-of-bounds heap read in `exec`/`test`/`match` via attacker-influenced `lastIndex` on a non-ASCII subject → uncatchable process crash (DoS)

Summary re2 validates the user-settable lastIndex against the subject's UTF-8 byte length but then uses it as a UTF-16 code-unit count to walk the subject buffer, with no bounds check. For any non-ASCII subject, the byte length is larger than the true character count, so a lastIndex between those...

EUVD-2026-51358

The GOOSE parser contains an off-by-one boundary-handling flaw that can be triggered by a single unauthenticated Layer-2 multicast frame on the process bus. When specific GOOSE message fields are processed, the parser advances its internal buffer position incorrectly, resulting in a heap...

EUVD-2026-51357

The MMS BER decoder contains a boundary-handling flaw in the processing of certain fields within confirmed-request messages. When a crafted BER-encoded element is received over an established MMS session TCP port 102, the decoder may advance its internal read position incorrectly, leading to a he...

CVE-2026-66369

CVE-2026-66360

The ISO Presentation layer contains a flaw in the handling of specific parameters during normal mode negotiation. A missing length check in the processing of the encoded presentation data allows an attacker controlled field with a zero length value to trigger a bounded heap over read. This...

CVE-2026-66349

The MMS server connection handler contains a flaw in its processing of BER-encoded request data. When an MMS confirmed request PDU containing an extended BER tag is received over an established session, the decoder may advance its internal buffer incorrectly due to a missing bounds check. This...

CVE-2026-63550

The MMS BER decoder contains a boundary-handling flaw in the processing of certain fields within confirmed-request messages.

CVE-2026-66349

The CVE-2026-66349 entry concerns the MMS server connection handler. A flaw in processing BER-encoded request data occurs when an MMS confirmed request PDU with an extended BER tag is received over an established session, where a missing bounds check can cause the decoder to advance its internal ...

CVE-2026-56758 MZ Automation libiec61850 Out-of-bounds Read

The ACSE layer contains a flaw in the processing of AARQ PDUs during MMS connection establishment. When parsing certain fields within the calling AP title, an attacker controlled length value of zero or one may cause the parser to read past the end of a heap buffer...

DEBIAN-CVE-2026-55777

GoAccess is a real-time web log analyzer and interactive viewer that runs in a terminal in nix systems or through the browser. Prior to 1.11, the parseios function uses an attacker-controlled keyword-to-OS offset as both the source offset and copy length for memmove, allowing a crafted User-Agent...

CVE-2026-55777

GoAccess (real-time web log analyzer/viewer) is affected by an out-of-bounds heap read in the parse_ios() function prior to version 1.11. A crafted User-Agent in a processed access log can cause memmove to use an attacker-controlled offset as both source offset and copy length, allowing reading u...
