Title
FFmpeg through 9.0.2 Double Free via cbs_sei_delete_message in cbs_sei.c
Summary
FFmpeg through 9.0.2 contains a double free vulnerability in libavcodec/cbs_sei.c where cbs_sei_delete_message() leaves a stale extension_data reference that ff_cbs_sei_add_message() reuses. Attackers can supply a crafted H.264 stream with a display orientation SEI message followed by payload extension data, processed by h264_metadata with display_orientation=insert, to corrupt heap memory.

Title
FreeRDP before 3.32.2 Double Free in WinPR Kerberos retrieveSomeTgt
Summary
FreeRDP before 3.32.2 contains a double free in the WinPR Kerberos SSPI retrieveSomeTgt function, which installs the krb5 default realm into a target principal that has an empty realm without taking ownership of it. Unauthenticated remote clients can send a crafted NLA/CredSSP u2u TGT request whose server-name component contains '@' to corrupt the heap and crash the server process.

Title
Tesseract: Double free and use after free in the PAGE XML renderer on right-to-left pages
Summary
Tesseract is an open source OCR engine. From 5.4.0 until 5.5.4, AppendLinePolygon in src/api/pagerenderer.cpp destroys the caller-owned right-to-left Pta accumulator while receiving it by value, leaving line_top_rtl_pts and line_bottom_rtl_pts dangling. On an upright Hebrew or Arabic page at the default PAGE XML level, POLYGONFLAG with a false skewed_flag enters the vulnerable calls, while LEVELFLAG greater than zero provides an alternative gate. The calls repeatedly read and free the stale object, causing a double free and use after free and allowing corrupted coordinates to reach RecalcPolygonline. This issue is fixed in version 5.5.4.

Title
Use-after-free in the SetClient command handler of kmstool-enclave in AWS aws-nitro-enclaves-sdk-c
Summary
A use-after-free and double-free issue in the SetClient command handler of the kmstool-enclave sample application of AWS aws-nitro-enclaves-sdk-c before 0.4.6 may allow an application that runs on the parent EC2 instance to corrupt heap memory inside a Nitro Enclave which may lead to arbitrary code execution within the enclave.
To remediate this issue, users should rebuild any enclave image that includes kmstool-enclave, or code derived from it, against aws-nitro-enclaves-sdk-c 0.4.6.

Title
L-SMASH through 2.14.5 Double Free in HEVC and H.264 Importer Probe
Summary
L-SMASH through 2.14.5 contains a double free vulnerability in hevc_setup_first_summary() and h264_setup_first_summary() in importer/nalu_imp.c that frees borrowed codec-specific objects on error paths. Attackers can supply a crafted Annex-B elementary stream lacking a parseable SPS to lsmash_read_file() or the boxdumper, remuxer, or muxer tools, causing use-after-free, heap corruption, and crashes.

Title
FreeRDP 3.29.0 before 3.32.0 Double Free via Async-Update Polygon Order
Summary
FreeRDP 3.29.0 before 3.32.0 contains a double free in the client's async-update message proxy, which shallow-copies the parser-owned PolygonSC or PolygonCB points array when numPoints is zero, so both the queue consumer and parser cleanup free it. A malicious RDP server can send a point-bearing polygon order followed by a zero-point order to crash a client with +async-update enabled.

Mitigation
Architecture and Design
Choose a language that provides automatic memory management.
Mitigation
Implementation
Ensure that each allocation is freed only once. After freeing a chunk, set the pointer to NULL to ensure the pointer cannot be freed again. In complicated error conditions, be sure that clean-up routines respect the state of allocation properly. If the language is object oriented, ensure that object destructors delete each chunk of memory only once.
Mitigation
Implementation
Use a static analysis tool to find double free instances.
