An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-45700 exists.\n\nAffected product: Freerdp Freerdp. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-45700/ (Markdown: https://insights.sbomify.com/CVE-2026-45700/index.md)","id":"CVE-2026-45700","markdown":"https://insights.sbomify.com/CVE-2026-45700/index.md","name":"CVE-2026-45700","record":{"aliases":["ALSA-2026:37207","ALSA-2026:38501","DEBIAN-CVE-2026-45700","GHSA-mpxh-8fq3-x8mh","MINI-9x4f-vmc6-2mw5","RHSA-2026:37207","RHSA-2026:38501","RHSA-2026:46383","RHSA-2026:46384","RHSA-2026:46388","RHSA-2026:46389","RHSA-2026:47048","RHSA-2026:47049","RHSA-2026:47201","RLSA-2026:37207","RLSA-2026:38501","UBUNTU-CVE-2026-45700","USN-8432-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"FreeRDP library","requires_auth":"none","summary":"An attacker can trigger a heap buffer overflow in FreeRDP's planar bitmap decoder, potentially leading to arbitrary code execution.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"freerdp","vendor":"freerdp"}],"cvss":{"score":7.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.26.0, FreeRDP's planar bitmap decoder has an out-of-bounds heap write when decoding RLE planar data. In libfreerdp/codec/planar.c, freerdp_bitmap_decompress_planar() validates the X destination coordinate nXDst against the caller-provided destination stride (nDstStep) even when it is writing into the internal temp buffer pTempData. An attacker can bypass the check with a large nDstStep and a large nXDst, causing planar_decompress_plane_rle() to write past the end of pTempData.
