Title
FreeRDP before 3.32.1 Android Client Heap OOB Read via Graphics Pipeline
Summary
FreeRDP before 3.32.1 contains a heap out-of-bounds read vulnerability in the Android client that allows malicious RDP servers to read beyond surface buffers by supplying unvalidated mappedWidth and mappedHeight values. Attackers can send a crafted RDPGFX_MAP_SURFACE_TO_WINDOW_PDU with oversized dimensions, causing android_UpdateWindowFromSurface to copy heap memory beyond the allocation, leading to crashes or memory disclosure.

Title
Vulnerability in FreeRDP
Summary
FreeRDP before 3.32.1 contains a heap-based out-of-bounds read in WinPR's clipboard PNG-to-CF_DIB synthesis because winpr_read_png_from_buffer() allocates a bit-packed buffer for PNGs with bit depth below 8, while winpr_bitmap_write_buffer() copies rows assuming one byte per pixel. A malicious RDP server can send a crafted low-bit-depth PNG clipboard payload that, when pasted by the victim, discloses megabytes of heap memory.

Title
FreeRDP before 3.32.1 Heap Out-of-Bounds Read via RD Gateway Consent Message
Summary
FreeRDP before 3.32.1 on Windows contains a heap out-of-bounds read in client_cli_present_gateway_message that passes a byte count as wide-character printf precision. A malicious RD Gateway can send pre-authentication consent or service messages, causing the client to read twice the buffer size, leaking heap memory or crashing.

CVE-2026-114038 (GCVE-0-2026-114038)

Vulnerability from cvelistv5 – Published: 2026-10-21 00:26 – Updated: 2026-10-21 00:26

Title
Device-mapper-multipath: device-mapper-multipath: information disclosure via malformed format string
Summary
A flaw was found in device-mapper-multipath. A local user can trigger an out-of-bounds read by sending a command with a format string ending in a trailing percent character to the multipath daemon. This issue can allow the user to expose unintended daemon memory, leading to information disclosure, or cause the daemon to crash, resulting in a Denial of Service (DoS).

CVE-2026-112896 (GCVE-0-2026-112896)

Title
Pillow: TIFF encoder ColorMap plane-size mismatch causes a heap out-of-bounds read
Summary
Pillow is a Python imaging library. Prior to 13.0.0, Pillow's TIFF encoder can read beyond a ColorMap buffer when retained TIFF metadata has a plane size inconsistent with BitsPerSample. A small TIFF can be opened normally and then retain a crafted ColorMap that is reused when the image is saved. An application that re-encodes the attacker's TIFF with libtiff can trigger the out-of-bounds read. This can disclose heap memory in the output or crash the process. This issue is fixed in version 13.0.0.

Title
libaribcaption 1.1.0 through 1.1.2 Out-of-Bounds Read via DecoderImpl::HandleGLGR
Summary
libaribcaption 1.1.0 through 1.1.2 contains a global out-of-bounds read in DecoderImpl::HandleGLGR() that reads past the 78-entry kLatinSpecialTable without an upper bound check. Attackers can supply crafted captions designating the Latin special set with ESC 28 4C followed by bytes 0x6F-0x7E to leak adjacent read-only data or crash decoding.

Title
VideoLAN libbluray through 1.5.1 Out-of-Bounds Read via clpi_access_point
Summary
VideoLAN libbluray through 1.5.1 contains an out-of-bounds read vulnerability in clpi_access_point() that allows attackers to crash applications by supplying a ClipInfo file with an empty EP-map fine table. Attackers can place a crafted .clpi file in BDMV/CLIPINF with num_ep_fine set to zero and an unclamped ref_ep_fine_id, triggering reads during seeking for denial of service.

Title
rdesktop through 1.9.0 Heap Out-of-Bounds Read via process_bmpcache2
Summary
rdesktop through 1.9.0 contains a heap out-of-bounds read vulnerability in process_bmpcache2() in orders.c that allows malicious RDP servers to crash clients via crafted revision-2 bitmap cache orders. Attackers can send an uncompressed order with large width/height or an underflowing mode nibble and short payload, causing memcpy() reads past the receive buffer and denial of service.

rdesktop through 1.9.0 contains a heap out-of-bounds read vulnerability in process_raw_bmpcache() in orders.c that allows malicious RDP servers to crash clients. Attackers can send a raw bitmap cache order declaring large width, height, and bpp values with a tiny payload, causing memcpy() to read past the receive buffer and crash the client.

Title
rdesktop through 1.9.0 Heap Out-of-Bounds Read via process_plane
Summary
rdesktop through 1.9.0 contains a heap out-of-bounds read vulnerability in process_plane() in bitmap.c that allows malicious RDP servers to crash clients by sending malformed 32 bpp compressed bitmaps. Attackers can declare a large bitmap geometry with a short compressed body in bitmap update PDUs or bitmap cache orders, causing unbounded reads past the receive buffer and denial of service.

Mitigation MIT-5
Implementation

Strategy: Input Validation

  • Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
  • When performing input validation, consider all potentially relevant properties, including length, type of input, the full range of acceptable values, missing or extra inputs, syntax, consistency across related fields, and conformance to business rules. As an example of business rule logic, "boat" may be syntactically valid because it only contains alphanumeric characters, but it is not valid if the input is only expected to contain colors such as "red" or "blue."
  • Do not rely exclusively on looking for malicious or malformed inputs. This is likely to miss at least one undesirable input, especially if the code's environment changes. This can give attackers enough room to bypass the intended validation. However, denylists can be useful for detecting potential attacks or determining which inputs are so malformed that they should be rejected outright.
  • To reduce the likelihood of introducing an out-of-bounds read, ensure that you validate and ensure correct calculations for any length argument, buffer size calculation, or offset. Be especially careful of relying on a sentinel (i.e. special character such as NUL) in untrusted inputs.
Mitigation
Architecture and Design

Strategy: Language Selection

Use a language that provides appropriate memory abstractions.

CAPEC-540: Overread Buffers

An adversary attacks a target by providing input that causes an application to read beyond the boundary of a defined buffer. This typically occurs when a value influencing where to start or stop reading is set to reflect positions outside of the valid memory location of the buffer. This type of attack may result in exposure of sensitive information, a system crash, or arbitrary code execution.
