CVE-2026-31806 1 Freerdp 1 Freerdp 2026-03-17 9.8 Critical
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.24.0, the gdi_surface_bits() function processes SURFACE_BITS_COMMAND messages sent by the RDP server. When the command is handled using NSCodec, the bmp.width and bmp.height values provided by the server are not properly validated against the actual desktop dimensions. A malicious RDP server can supply crafted bmp.width and bmp.height values that exceed the expected surface size. Because these values are used during bitmap decoding and memory operations without proper bounds checking, this can lead to a heap buffer overflow. Since the attacker can also control the associated pixel data transmitted by the server, the overflow may be exploitable to overwrite adjacent heap memory. This vulnerability is fixed in 3.24.0.
CVE-2026-31883 1 Freerdp 1 Freerdp 2026-03-17 6.5 Medium
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.24.0, a size_t underflow in the IMA-ADPCM and MS-ADPCM audio decoders leads to heap-buffer-overflow write via the RDPSND audio channel. In libfreerdp/codec/dsp.c, the IMA-ADPCM and MS-ADPCM decoders subtract block header sizes from a size_t variable without checking for underflow. When nBlockAlign (received from the server) is set such that size % block_size == 0 triggers the header parsing at a point where size is smaller than the header (4 or 8 bytes), the subtraction wraps size to ~SIZE_MAX. The while (size > 0) loop then continues for an astronomical number of iterations. This vulnerability is fixed in 3.24.0.
CVE-2026-4177 1 Toddr 1 Yaml::syck 2026-03-17 9.1 Critical
YAML::Syck versions through 1.36 for Perl has several potential security vulnerabilities including a high-severity heap buffer overflow in the YAML emitter. The heap overflow occurs when class names exceed the initial 512-byte allocation. The base64 decoder could read past the buffer end on trailing newlines. strtok mutated n->type_id in place, corrupting shared node data. A memory leak occurred in syck_hdlr_add_anchor when a node already had an anchor. The incoming anchor string 'a' was leaked on early return.
CVE-2025-69808 1 P2r3 1 Bareiron 2026-03-17 9.1 Critical
An out-of-bounds memory access (OOB) in p2r3 Bareiron commit 8e4d40 allows unauthenticated attackers to access sensitive information and cause a Denial of Service (DoS) via supplying a crafted packet.
CVE-2025-69809 1 P2r3 1 Bareiron 2026-03-17 9.8 Critical
A write-what-where condition in p2r3 Bareiron commit 8e4d40 allows unauthenticated attackers to write arbitrary values to memory, enabling arbitrary code execution via a crafted packet.
CVE-2026-0708 1 Libucl 1 Libucl 2026-03-17 8.3 High
A flaw was found in libucl. A remote attacker could exploit this by providing a specially crafted Universal Configuration Language (UCL) input that contains a key with an embedded null byte. This can cause a segmentation fault (SEGV fault) in the `ucl_object_emit` function when parsing and emitting the object, leading to a Denial of Service (DoS) for the affected system.
CVE-2025-30415 2026-03-17 N/A
Denial of service due to improper handling of malformed input. The following products are affected: Acronis Cyber Protect Cloud Agent (Linux, macOS, Windows) before build 40077, Acronis Cyber Protect 17 (Linux, macOS, Windows) before build 41186.
CVE-2026-4167 1 Belkin 2 F9k1122, F9k1122 Firmware 2026-03-17 8.8 High
A vulnerability was determined in Belkin F9K1122 1.00.33. This affects the function formReboot of the file /goform/formReboot. This manipulation of the argument webpage causes stack-based buffer overflow. The attack may be initiated remotely. The exploit has been publicly disclosed and may be utilized. The vendor was contacted early about this disclosure but did not respond in any way.
CVE-2026-31885 1 Freerdp 1 Freerdp 2026-03-17 6.5 Medium
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.24.0, there is an out-of-bounds read in MS-ADPCM and IMA-ADPCM decoders due to unchecked predictor and step_index values from input data. This vulnerability is fixed in 3.24.0.
CVE-2026-31897 1 Freerdp 1 Freerdp 2026-03-17 0 Low
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.24.0, there is an out-of-bounds read in freerdp_bitmap_decompress_planar when SrcSize is 0. The function dereferences *srcp (which points to pSrcData) without first verifying that SrcSize >= 1. When SrcSize is 0 and pSrcData is non-NULL, this reads one byte past the end of the source buffer. This vulnerability is fixed in 3.24.0.
CVE-2025-14905 1 Redhat 6 Directory Server, Directory Server Eus, Enterprise Linux and 3 more 2026-03-17 7.2 High
A flaw was found in the 389-ds-base server. A heap buffer overflow vulnerability exists in the `schema_attr_enum_callback` function within the `schema.c` file. This occurs because the code incorrectly calculates the buffer size by summing alias string lengths without accounting for additional formatting characters. When a large number of aliases are processed, this oversight can lead to a heap overflow, potentially allowing a remote attacker to cause a Denial of Service (DoS) or achieve Remote Code Execution (RCE).
CVE-2025-71264 1 Mumble 1 Mumble 2026-03-17 3.7 Low
Mumble before 1.6.870 is prone to an out-of-bounds array access, which may result in denial of service (client crash).
