• Re: Apple’s A17 Pro Chip: Critical Flaw Causes Dual Subsystem Failure & Forensic Log Loss September 11, 2025
  Posted by Matthew Fernandez on Sep 10Can you elaborate on why you consider this high severity? From the description, it sounds as if this behaviour is fail-closed. That is, the effects are limited to DoS, with security properties preserved.

• FFmpeg 7.0+ Integer Overflow in FFmpeg cache: Protocol (CacheEntry::size) September 8, 2025
  Posted by Ron E on Sep 08An integer overflow vulnerability exists in the FFmpeg cache: URL protocol implementation. The CacheEntry structure uses a 32-bit signed integer to store cache entry sizes (int size), but the cache layer can accumulate cached data exceeding 2 GB. Once entry->size grows beyond INT_MAX and new data is appended, an […]
• FFmpeg 7.0+ Integer Overflow in DSCP Option Handling of FFmpeg UDP Protocol September 8, 2025
  Posted by Ron E on Sep 08A vulnerability exists in the FFmpeg UDP protocol implementation ( libavformat/udp.c) where the dscp parameter is parsed from a URI and left-shifted without bounds checking. Supplying a maximum 32-bit signed integer (2147483647) triggers undefined behavior due to a left shift that exceeds the representable range of int. This results […]
• FFmpeg 7.0+ Integer Overflow in UDP Protocol Handler (fifo_size option) September 8, 2025
  Posted by Ron E on Sep 08A signed integer overflow exists in FFmpeg’s udp.c implementation when parsing the fifo_size option from a user-supplied UDP URL. The overflow occurs during multiplication, which is used to compute the size of the circular receive buffer. This can result in undefined behavior, allocation failures, or potentially memory corruption depending […]
• FFmpeg 7.0+ LADSPA Filter Arbitrary Shared Object Loading via Unsanitized Environment Variables September 8, 2025
  Posted by Ron E on Sep 08The ladspa audio filter implementation (libavfilter/af_ladspa.c) in FFmpeg allows unsanitized environment variables to influence dynamic library loading. Specifically, the filter uses getenv("LADSPA_PATH") and getenv("HOME") when resolving the plugin shared object (.so) name provided through the file option. These values are concatenated into a filesystem path and passed directly into […]
