  Posted by Ron E on Sep 08 An 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 … Read More “FFmpeg 7.0+ Integer Overflow in FFmpeg cache: Protocol (CacheEntry::size)  – Full Disclosure” »

  Posted by Ron E on Sep 08 The DjVuLibre document compression library (tested version 3.5.29) is vulnerable to an integer overflow caused by a left shift of a negative signed integer in the IW44EncodeCodec.cpp component. When processing crafted PPM input passed through the c44 utility, negative pixel values are left-shifted in functions such as … Read More “DjVuLibre 3.5.29 IW44EncodeCodec Integer Overflow (Negative Left Shift in IW44Image::Map::Encode)  – Full Disclosure” »

  Posted by Ron E on Sep 08 The DjVuLibre document compression library (tested version 3.5.29) contains multiple instances of unsigned integer overflow in the ZPCodec.cpp component. During arithmetic encoding operations (e.g., zemit, encode_lps, encode_lps_simple, eflush), crafted input can cause arithmetic wraparound (0-1, 1-2, or value+UINT_MAX). These operations rely on precise probability modeling for entropy … Read More “DjVuLibre 3.5.29 ZPCodec Unsigned Integer Overflow in Arithmetic Encoding  – Full Disclosure” »

  Posted by Ron E on Sep 08 The 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 … Read More “FFmpeg 7.0+ LADSPA Filter Arbitrary Shared Object Loading via Unsanitized Environment Variables  – Full Disclosure” »

  Posted by Ron E on Sep 08 A 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 … Read More “FFmpeg 7.0+ Integer Overflow in UDP Protocol Handler (fifo_size option)  – Full Disclosure” »

  Posted by Ron E on Sep 08 A 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. … Read More “FFmpeg 7.0+ Integer Overflow in DSCP Option Handling of FFmpeg UDP Protocol  – Full Disclosure” »

  Posted by Ron E on Sep 08 The FFmpeg tools/yuvcmp utility is vulnerable to an integer overflow when large width and height parameters are supplied. The overflow occurs during buffer size calculations (width * height) leading to incorrect allocation sizes and subsequent memory corruption. An attacker controlling input dimensions can trigger large or invalid … Read More “FFmpeg 7.0+ Integer Overflow in FFmpeg yuvcmp Tool Leads to Out-of-Bounds Allocation  – Full Disclosure” »

  Posted by Ron E on Sep 08 FFmpeg invokes function pointers through incorrect type casting, leading to type confusion. UndefinedBehaviorSanitizer logs mismatched signatures in utils.c:528. Crafted inputs can cause UB, misaligned function dispatch, and possible arbitrary code execution depending on platform ABI. (FFmpeg 7.0 – 8.0) *Impact:* – DoS in normal builds. – Potential … Read More “FFmpeg 7.0+ Type Confusion in FFmpeg Function Pointer Calls (libavformat/utils.c)  – Full Disclosure” »

  Posted by Ron E on Sep 08 Improper validation in libavutil/avstring.c allows a NULL pointer dereference when processing certain strings in HLS contexts. UBSan reports “applying zero offset to null pointer.” Triggers denial of service (DoS) when FFmpeg processes malicious playlists or malformed URLs. (FFmpeg 7.0 – 8.0) *Impact:* – Consistently crashes the process … Read More “FFmpeg 7.0+ NULL Pointer Dereference in FFmpeg String Handling (avstring.c)  – Full Disclosure” »

  Posted by Ron E on Sep 08 Malformed .m3u8 playlists can trigger a heap use-after-free when the HLS demuxer handles segment references. ASan reports access to freed memory inside libavformat/utils.c:528. A crafted .m3u8 could allow remote attackers to achieve denial of service (DoS), information disclosure, or potentially remote code execution depending on heap state. … Read More “FFmpeg 7.0+ Heap Use-After-Free in FFmpeg HLS Demuxer (libavformat/utils.c)  – Full Disclosure” »

  Posted by Ron E on Sep 08 The FullBox::get_flags() method retrieves 24-bit flags from the underlying box header. When a malformed box truncates the field, the function still attempts to read three bytes. With insufficient data, this reads past valid memory into uninitialized or out-of-bounds memory. *Root Cause:* – No length validation before reading … Read More “libheif v1.21.0 Out-of-Bounds Read in FullBox::get_flags  – Full Disclosure” »

  Posted by Ron E on Sep 08 Box_hdlr::get_handler_type() (libheif/box.h:487) is called even when the hdlr box has not been properly initialized due to malformed input. This leads to dereferencing a null object pointer. *Root Cause:* – No validation of hdlr box presence before accessing handler fields. *Impact:* – Application crash only (DoS). – No … Read More “libheif v1.21.0 Null Pointer Dereference in Box_hdlr::get_handler_type  – Full Disclosure” »

  Posted by Ron E on Sep 08 During construction of a Track_Visual object, corrupted sequence metadata can leave a std::vector<unsigned> uninitialized. When .empty() is called, it attempts to dereference a null object. *Root Cause:* – Missing input validation when constructing vectors from parsed boxes. *Impact:* – Application crash (DoS). – Not exploitable for code … Read More “libheif v1.21.0 Null Pointer Dereference in std::vector::empty  – Full Disclosure” »

  Posted by Ron E on Sep 08 An integer overflow vulnerability exists in the Y4M input loader (loadY4M in decoder_y4m.cc) of libheif. The loader fails to properly validate the width and height values declared in the Y4M file header. Supplying a crafted .y4m file with extremely large dimensions (e.g., W2147483647 H2147483647) causes integer overflow … Read More “libheif v1.21.0 Integer Overflow in Y4M Loader leading to Uncontrolled Memory Allocation  – Full Disclosure” »

  Posted by Ron E on Sep 08 The vulnerability resides in the constructor Chunk::Chunk ( libheif/sequences/chunk.cc:89). When parsing the Sample Size Box (stsz) of a HEIF sequence track, the code allocates a std::vector<unsigned int> and then appends entries for each sample size. The count used for allocation and iteration is taken directly from the … Read More “libheif v1.21.0 Heap Buffer Overflow in Chunk::Chunk  – Full Disclosure” »

  Posted by Ron E on Sep 08 The Track::init_sample_timing_table logic manages a std::vector<std::shared_ptr<Chunk>> representing parsed sequence chunks. With malformed HEIF sequence files, corrupted chunk tables may cause premature destruction of Chunk objects while references remain in the vector. Later accesses via std::__shared_ptr<Chunk>::get() return a dangling pointer. ASan reports these as heap-buffer-overflows because the stale … Read More “libheif 1.21.0 Use-After-Free / Dangling shared_ptr in Track Chunk Handling  – Full Disclosure” »

  Posted by Ron E on Sep 08 The Box_stts structure defines decoding time to sample mapping. In Box_stts::get_sample_duration(unsigned), the requested index is assumed valid. A crafted file can set entry_count inconsistently with the actual buffer size, leading to access beyond the bounds of the parsed vector. *Root Cause:* – Lack of bounds checks on … Read More “libheif v1.21.0 Out-of-Bounds Read in Box_stts::get_sample_duration  – Full Disclosure” »
