Miniaudio out-of-bounds write vulnerability 

Discovered by Emmanuel Tacheau of Cisco Talos.   

TALOS-2024-2063 (CVE-2024-41147) is an out-of-bounds write vulnerability in Miniaudio, a lightweight, single-file audio playback and capture library written in C. A missing allocation size check can cause a buffer overflow, leading to this out-of-bounds write. This vulnerability can be triggered by a specially crafted FLAC file, resulting in a memory corruption when in playback mode. The application sends raw audio data to Miniaudio, which is then played back through the default playback device as defined by the operating system. 

Adobe Acrobat out-of-bounds write vulnerability 

Discovered by KPC of Cisco Talos.   

TALOS-2025-2134 (CVE-2025-27163) and TALOS-2025-2136 (CVE-2025-27164) are out-of-bounds read vulnerabilities in the font functionality, which can lead to disclosure of sensitive information. TALOS-2025-2135 (CVE-2025-27158) is a memory corruption vulnerability, stemming from an uninitialized pointer in the font functionality of Adobe Acrobat, which can potentially lead to arbitrary code execution. A specially crafted font file embedded into a PDF can trigger these vulnerabilities. An attacker needs to trick the user into opening a malicious file.
