Mongoose is an embedded web server and network library. Prior to 7.23, the built-in TLS stack selected by MG_TLS_BUILTIN in src/tls_builtin.c accepts a TLS 1.3 record whose decrypted size is exactly the 16-byte authentication tag with no plaintext or ContentType byte. In mg_tls_recv_record(), the msgsz length check permits that record and the recv_len calculation underflows to SIZE_MAX, so a later handshake step treats stale buffer contents as a trusted message with an effectively unbounded length. An unauthenticated malicious TLS peer can trigger a heap out-of-bounds read before certificate or Finished validation, causing a remote denial of service. This issue is fixed in version 7.23.

A NULL Pointer Dereference vulnerability in the routing-policy nexthop-ECMP matcher of Juniper Networks Junos OS and Junos OS Evolved allows a configured eBGP peer to cause a routing-daemon denial of service via a specific BGP packet received while a nexthop-ecmp qualifier is attached to a BGP import policy.

Successful exploitation can crash rpd and interrupt routing protocols until the daemon restarts and reconverges.

A Missing Release of Memory after Effective Lifetime vulnerability in the packet forwarding engine (PFE) of Juniper Networks Junos OS on SRX Series allows an unauthenticated, network-based attacker to cause a complete Denial-of-Service (DoS). On SRX4000 Series, and SRX5000 Series with SPC3, and MX Series with SPC3, when one or more specific application services like ALGs, IDP/DPI, APPID, SECINTEL, AAMW or AppQoE are configured, a high connections per second churn will cause PFE memory to leak. If the memory is exhausted traffic processing will be impacted. Use the CLI command show security monitoring to monitor the memory utilization of the PFEs on the FPCs. This issue affects Junos OS on SRX Series and MX Series: * 23.4 versions from 23.4R2-S3 before 23.4R2-S7; * 24.2 versions from 24.2R2 before 24.2R2-S3; * 24.4 versions before 24.4R2-S3; * 25.2 versions before 25.2R1-S2, 25.2R2.

FreeSWITCH is a Software Defined Telecom Stack enabling the digital transformation from proprietary telecom switches to a software implementation that runs on any commodity hardware. Prior to 1.11.2, rtmp_rtp2rtmpH264() built an AVC decoder configuration record in a fixed stack buffer by copying wire-derived SPS and PPS values without checking that their sizes and framing fit. An established H.264 call bridged toward an RTMP endpoint could supply oversized SPS and PPS parameter sets and overrun the function's stack frame. The flaw affects only deployments that build and load mod_rtmp and bridge RTP media into an RTMP leg; the module is disabled in the stock build and configuration. The corruption can abort FreeSWITCH and terminate every active call, and builds without stack protection receive a limited stack-write primitive, although code execution has not been demonstrated. This issue is fixed in version 1.11.2.

PyMuPDF 1.25.3 before 2.0 contains a stack-based buffer overflow vulnerability in JM_set_annot_callout_line() that copies a caller-supplied number of callout points into a fixed three-element stack array. Attackers who control the callout argument passed to Page.add_freetext_annot() can supply four or more points to overwrite the stack frame, crashing the process or executing code.

FreeRDP 2.0.0 before 3.32.0, when built with WITH_LAME=ON and WITH_DSP_FFMPEG=OFF, has a heap-based buffer overflow in freerdp_dsp_decode_mp3 because the right-channel PCM pointer is offset by a byte count treated as short elements. A malicious RDP server can send MP3 audio over rdpsnd so decoded samples cross the heap allocation, crashing the client.

SIPSorcery is a WebRTC, SIP, and VoIP library for C# and .NET. Prior to 10.0.14, SctpSackChunk.ParseChunk reads the numGapAckBlocks and numDuplicateTSNs fields from an attacker-controlled SCTP SACK chunk without checking that the corresponding entries fit the declared chunk length. A negotiated WebRTC peer can send a checksum-valid malformed SACK chunk that drives the parser beyond the 262144-byte receive buffer. The resulting IndexOutOfRangeException bypasses the recoverable ApplicationException handler in RTCSctpTransport.DoReceive, causing the generic handler to exit the dedicated receive loop and permanently terminate the SCTP association and all data channels. This issue is fixed in 10.0.14.

In Eclipse OpenJ9 versions prior to 0.63.0, the JITServer component fails to perform cross-field validation on attacker-controlled `_size`, `_paddingSize`, and `_dataOffset` fields during `DataDescriptor` message deserialization. An unauthenticated remote attacker can send a crafted network payload that triggers an unsigned integer underflow in `DataDescriptor::getPayloadSize()` and `DataDescriptor::getNextDescriptor()`. This results in an out-of-bounds heap read and an immediate process crash (SIGSEGV), causing a denial of service.

kin-openapi is a Go project for handling OpenAPI files. Prior to 0.145.0, openapi3.Loader can dereference a nil SchemaRef.Value while resolving a self-referential additionalProperties JSON Reference such as a schema that points to its own additionalProperties member. Loading an attacker-controlled OpenAPI document through LoadFromData, LoadFromFile, or LoadFromURI reaches resolveComponent before document validation and can panic the loading process. Resolved additionalProperties schemas and ordinary recursive schemas do not take the vulnerable nil-value path. This issue is fixed in version 0.145.0.

The VobSub subtitle decoder libsub_vob (part of the Amlogic DroidLogic SubTitleService), as shipped on Nexbox A95X (Amlogic S905X) TV boxes, contains an out-of-bounds write vulnerability in vob_fill_pixel() that allows remote attackers to corrupt stack memory by sending a crafted SET_CONTR command with an attacker-controlled alpha value that drives an unbounded array index (change_data) past the end of the fixed four-element PixelDatas array. Attackers can exploit this by sending malicious VobSub data over the unauthenticated tcp/10100 socket or via a malicious .sub file to zero out adjacent stack bytes, resulting in silent stack corruption or process crash.

RIOT is an open-source microcontroller operating system designed for Internet of Things devices and other embedded systems. Prior to 2026.07, _parse_reply() in sys/net/application_layer/dhcpv6/client.c omits minimum-length validation before passing IA_PD and IA_NA option bodies to sub-option parsers. A malicious or compromised DHCPv6 server can send a REPLY with an option length smaller than the required structure while MODULE_DHCPV6_CLIENT_IA_PD is enabled, causing _parse_ia_pd_option to read past the option body, size_t underflow, and unbounded out-of-bounds heap reads that can crash the device and may expose or corrupt memory. This issue is fixed in version 2026.07.

libIEC61850 is an open-source implementation of IEC 61850 client and server protocols including MMS, GOOSE, Sampled Values, and R-Session. Prior to 1.6.2, checkDataSetAccess reverses the source and destination arguments to StringUtils_copyStringToBuffer while constructing an MMS_ASSOCIATION_SPECIFIC dataset reference. The helper treats uninitialized dataSetRef[130] storage as a source string, causing strlen to read beyond the stack buffer, and then copies those bytes into the caller-owned listName buffer. A remote defineNamedVariableList request can crash servers that have dynamic dataset service enabled and a dataset access handler installed; the advisory also observes caller stack corruption but establishes denial of service as the primary impact. This issue is fixed in version 1.6.2.
