Integer overflow or wraparound vulnerability in Samsung Open Source rlottie allows Overflow Buffers.
This issue affects .
AnalysisAI
Integer overflow in Samsung's open-source rlottie animation rendering library leads to buffer overflow, with high availability impact including potential crash or memory corruption. Exploitation requires local access, low privileges, user interaction, and high attack complexity, making this a lower-urgency finding despite the buffer overflow class. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires: (1) local access to the target system (AV:L), meaning the attacker must already be present on the machine or deliver a malicious file to the local filesystem; (2) low-privilege authenticated access (PR:L) - unauthenticated remote exploitation is not supported by the CVSS vector; (3) user interaction (UI:R), specifically the victim must open or render a crafted Lottie animation file using an application embedding the vulnerable rlottie library; (4) high attack complexity (AC:H), indicating that specific conditions - likely related to memory layout, heap state, or file structure - must be met for reliable exploitation. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 score of 5.5 (Medium) with vector AV:L/AC:H/PR:L/UI:R/S:U/C:L/I:L/A:H accurately reflects a constrained threat model: exploitation requires local system presence, low-level authenticated access, active user interaction (e.g., opening a crafted animation file), and high attack complexity implying that specific preconditions or memory layout conditions must be satisfied. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts a malicious Lottie animation file (.json) engineered to trigger the integer overflow during parsing or frame rasterization within rlottie. The attacker delivers the file to a target system (e.g., via messaging app, file share, or embedded in a document) and induces the victim to open or preview it in an application that uses rlottie for rendering, causing an out-of-bounds write that crashes the host application or, under conditions requiring high attack complexity, corrupts adjacent memory. … |
| Remediation | Apply the upstream fix available in Samsung rlottie GitHub pull request #595 (https://github.com/Samsung/rlottie/pull/595). … Detailed patch versions, workarounds, and compensating controls in full report. |
