CVE Database

ImageMagick 7.1.0-21 before 7.1.2-32 contains a heap buffer over-read in its handling of the -fx option, where a certain -fx operation reads beyond the bounds of an allocated heap buffer in specific situations. Attackers who can get a crafted -fx expression processed can read out-of-bounds heap memory, potentially disclosing limited memory contents.

ImageMagick 7.1.0-20 before 7.1.2-32 contains a use after free vulnerability in the -fx option that occurs when a memory allocation fails during a specific operation. Attackers who can supply crafted -fx expressions under memory pressure can trigger freed memory access, causing crashes or memory corruption.

ImageMagick before 7.1.2-32 contains a policy bypass vulnerability in the -script operation due to missing checks on file descriptor handling. Attackers can use the -script operation to close file descriptors not opened by the current operation, circumventing configured security policies.

ImageMagick before 6.9.13-57 and 7.x before 7.1.2-32 contains an incomplete cleanup flaw in the JNG decoder that fails to remove temporary files when processing crafted input. Attackers can submit crafted JNG files for processing to repeatedly leak temporary files, consuming disk space and degrading availability.

ImageMagick before 6.9.13-57 and 7.x before 7.1.2-32 contains a code injection vulnerability in the MVG decoder when a PostScript renderer is used. Attackers can supply a crafted MVG file that, when decoded, injects code into the PostScript rendering path.

ImageMagick 7.1.1-31 before 7.1.2-32 contains a NULL pointer dereference in the PostScript decoder that is triggered when a policy limit is reached. Attackers can supply a crafted PostScript file for processing to crash the application, causing a denial of service.

ImageMagick 7.1.2-30 before 7.1.2-32 contains a use after free vulnerability in the WBINFO decoder that occurs when a memory allocation fails during image decoding. Attackers can supply a crafted image that, when decoded under memory allocation failure conditions, causes freed memory to be reused, crashing the application.

ImageMagick before 7.1.2-32 contains a memory leak vulnerability in the -process option that allows attackers to cause unreleased memory allocations by supplying certain arguments. Attackers can repeatedly invoke the -process option with crafted arguments to gradually exhaust memory and degrade service availability.

ImageMagick before 6.9.13-57 and 7.x before 7.1.2-32 contains a stack overflow in the MSL decoder caused by an incorrect depth check that fails to limit recursion. Attackers can supply a set of crafted MSL images that exhaust the stack when one of them is read, crashing the process and causing a denial of service.

ImageMagick before 6.9.13-57 and 7.x before 7.1.2-32 contains an XML injection vulnerability in the CIP encoder, which does not properly escape input-derived data when writing Cisco IP Phone XML output. Attackers can supply a crafted file that, when converted to CIP format, injects arbitrary markup into the generated XML.

ImageMagick 7.1.1-7 before 7.1.2-32 contains a heap buffer over-read vulnerability that allows attackers to read beyond allocated memory due to incorrect string termination in XMP profiles. Attackers can supply a crafted image containing a malformed XMP profile to trigger the over-read and crash the application.

ImageMagick before 6.9.13-57 and 7.x before 7.1.2-32 contains a memory leak in the SVG encoder (WriteSVGImage) that fails to release allocated memory when handling crafted images. Attackers can supply crafted image files that are processed by the SVG encoder to leak memory and cause a denial of service through resource consumption.

ImageMagick before 6.9.13-57 and 7.x before 7.1.2-32 contains a memory leak in the GIF encoder because allocated memory is not released when color quantization fails during encoding. Attackers can supply images whose GIF conversion causes quantization to fail, leaking memory with each attempt and degrading availability.

ImageMagick before 6.9.13-57 and 7.x before 7.1.2-32 contains a memory leak in the PNG encoder, which does not release allocated memory when libpng initialization fails. Attackers who can repeatedly trigger PNG encoding operations in which libpng initialization fails can exhaust memory and cause a denial of service.

FreeRDP before 3.32.0 contains a double-free vulnerability in nsc_context_initialize_encode() that leaves dangling plane pointers after a partial buffer growth failure. Attackers using a crafted RDP client can negotiate NSCodec with a large desktop geometry to trigger allocation failure, crashing the server during context teardown.

FreeRDP 3.10.0 through 3.32.2 contains a heap buffer overflow in the WinPR png_write_data callback that writes past the buffer after a realloc failure. A malicious RDP clipboard peer can supply a large CF_DIB image that triggers out-of-bounds memcpy during PNG conversion, causing a client crash.

FreeRDP 3.0.0 before 3.32.0 contains an integer truncation vulnerability in license_check_stream_length that allows a malicious RDP server to trigger a heap buffer overflow on 32-bit clients. Attackers can send a crafted SERVER_LICENSE_REQUEST with a large scopeCount that bypasses length checks, causing out-of-bounds writes leading to denial of service or remote code execution.

FreeRDP from 3.9.0 before 3.32.0 contains a NULL pointer dereference vulnerability in the RDPEAR NDR reader that allows malicious servers to crash clients via truncated KERB_RPC_INTERNAL_NAME data. Attackers can send a CreateApReqAuthenticatorReq with NameCount of two or more ending before the Names pointer, causing cleanup to dereference a null base and terminate the client.

FreeRDP before 3.32.0 stores the server-supplied signed MS-RDPEGT geometry origin unchecked in an unsigned video surface coordinate, so the blit clamp in gdiVideoShowSurface() wraps in 32-bit arithmetic and is skipped. A malicious RDP server can send a negative topLevelLeft to clients connecting with /video, causing an out-of-bounds write of decoded H.264 picture data or a client abort.

FreeRDP 3.0.0 before 3.32.0 contains a heap buffer overflow vulnerability in collect_keys() that allows local attackers to write past the fixed 64-entry keys array during PKCS#11 key enumeration. Attackers controlling smartcard tokens can present more than 64 public key objects across multiple slots to corrupt heap memory with attacker-chosen CKA_ID and CKA_LABEL data during smartcard logon.

FreeRDP before 3.32.0 contains a path traversal vulnerability in convert_filedescriptors_to_file_list() in winpr/libwinpr/clipboard/synthetic_file.c, which concatenates server-supplied cFileName values from FileGroupDescriptorW clipboard data into the published local file:// URI without rejecting '/' or '..' sequences. A malicious RDP server can supply '../' sequences so the user's next clipboard paste copies an arbitrary local file readable by the client user instead of the expected remote file.

FreeRDP before 3.32.0 contains a divide-by-zero vulnerability in the freerdp-shadow-cli shadow server: the frame id in a client's Frame Acknowledge PDU is stored without a range check, so the in-flight frame count in shadow_encoder_inflight_frames() can underflow. An authenticated client can acknowledge a frame id one greater than the last frame sent, causing shadow_encoder_create_frame_id() to divide by zero (SIGFPE) and terminate the process, disconnecting all viewers.

FreeRDP 3.0.0 before 3.32.0 contains an improper certificate validation vulnerability in freerdp_http_request() in libfreerdp/utils/http.c that completes TLS handshakes without verifying the server certificate chain. On-path attackers can impersonate login.microsoftonline.com in the Azure AD authentication flow to capture OAuth authorization codes and substitute the OpenID discovery document.

FreeRDP before 3.0.0 and 3.6.0 before 3.32.0 renders uninitialized heap memory from un-decoded progressive tiles because the tile->current buffer is allocated without zeroing. A malicious RDP server can send a crafted WBT_TILE_FIRST then WBT_TILE_UPGRADE sequence to paint heap bytes onscreen or abort the client process.

FreeRDP before 3.32.0 contains a NULL pointer dereference vulnerability in the client video redirection channel that allows malicious servers to crash clients by sending out-of-order messages. Attackers can send a Geometry CLEAR message that nulls presentation->geometry, then send VideoData that dereferences it, causing client denial of service.
