Descrição técnica

Ettercap through 0.8.4.1 contains a heap out-of-bounds read vulnerability in sslw_get_clienthello_sni() in src/ec_sslwrap.c that trusts the unchecked 16-bit SNI length field. Network-adjacent attackers can send crafted TLS ClientHello messages during SSL interception to leak up to 64 KB of heap memory upstream or crash Ettercap.

CVE-2026-149185.3 MÉD

—

———The Signed Video Framework contained a out-of-bounds read issue in the Signed Video Framework which could lead the application using this framework to crash. The issue exclusively affects the tools used for the validation of signed content. The AXIS OS device's signed video functionality remains unaffected.6h CVE-2026-1098067.5 ALT

—

———SAP NetWeaver (Internet Graphics Service) does not sufficiently validate certain input values within incoming requests. An unauthenticated user could send a specially crafted request containing malformed image data, triggering an integer overflow that leads to repeated termination of the worker process. This results in a high impact on availability with no impact on integrity or confidentiality.11h CVE-2026-1254058.1 ALT

—

———Ettercap through 0.8.4.1 contains an out-of-bounds read vulnerability in Parse_NTLM_Auth() in src/dissectors/ec_http.c due to unvalidated NTLM message offsets. Attackers can send a crafted HTTP Authorization header observed by Ettercap to read beyond the buffer, disclosing memory or crashing the process.12h CVE-2026-1254038.1 ALT

—

———Ettercap through 0.8.4.1 contains an out-of-bounds read and size_t underflow vulnerability in sslw_remove_sts() in src/ec_sslwrap.c, caused by a stale length and an unchecked memmem() result when stripping Strict-Transport-Security headers. A malicious HTTPS server whose response passes through Ettercap's SSL interception can trigger out-of-bounds reads and memory corruption in the Ettercap process, which normally runs as root.12h CVE-2026-905883.7 BAI

———The HTTP client's debug helper print_header_field() in subsys/net/lib/http/http_client.c formatted an http_parser data-callback slice with a %s conversion: snprintk(output, len + 1, "%s", str). The parser hands its callbacks a pointer and a length into the caller's receive buffer, and those bytes are not NUL terminated. The size argument of snprintk() bounds only the destination, while the %s conversion measures the source first — lib/os/cbprintf_complete.c uses strlen() when no precision is given, and lib/os/cbprintf_nano.c uses strlen() unconditionally — so the read walks past the end of the header field and past the end of the receive buffer until it finds a zero byte. The slice reaches the helper from on_url(), on_header_field() and on_header_value(), which the parser invokes on bytes that http_wait_data() read straight off the socket into the application-supplied recv_buf. A malicious or compromised HTTP server, or an attacker able to answer a plaintext request, therefore controls both the header field and the bytes that follow it in the buffer, and can guarantee that no zero byte appears before the buffer ends, forcing the over-read. The in-tree tests/net/lib/http_client suite reproduces the over-read under CONFIG_ASAN=y on an ordinary GET. The impact is bounded. The whole helper body is compiled only when the HTTP client log module is explicitly set to Debug (CONFIG_NET_HTTP_LOG_LEVEL_DBG=y, which the global CONFIG_LOG_DEFAULT_LEVEL does not set), so default builds are unaffected. No out-of-bounds write occurs and none of the over-read bytes are emitted into the log, so there is no information disclosure; the consequence is an out-of-bounds read that can fault and panic the device where the buffer abuts an unmapped or MPU/MMU-protected region. The fix copies exactly the len bytes the parser offered with memcpy() and terminates them, instead of relying on a %s conversion (a %.*s precision would not have sufficed, since cbprintf_nano.c measures the source in full before applying it).13h CVE-2026-1249966.3 MÉD

———A weakness has been identified in Turboderp-org ExLlamaV3 up to 1.6.3. The impacted element is the function routing_sel_norm_kernel of the file exllamav3/exllamav3_ext/routing.cu of the component hash-MoE routing. This manipulation of the argument gate.tid2eid causes out-of-bounds read. Remote exploitation of the attack is possible. Upgrading to version 1.6.4 is sufficient to resolve this issue. Patch name: c9a57ae832a3035e264e0a412e1daf4ebb699b98. Upgrading the affected component is recommended.13h
