TinyUSB < 0.21.0 Integer Underflow via HID Report Descriptor Parser

TinyUSB before 0.21.0 contains an integer underflow vulnerability in the HID host report descriptor parser tuh_hid_parse_report_descriptor() in src/class/hid/hid_host.c that allows a malicious USB device to trigger an out-of-bounds read by subtracting an item size from the remaining descriptor length without validating the item fits within the remaining buffer. Attackers can present a crafted USB device with a truncated report descriptor causing the uint16_t desc_len value to underflow, resulting in out-of-bounds memory reads and denial of service on the host system.

FFmpeg through 9.0.2 Heap Overflow via Nellymoser Encoder Trellis Search

FFmpeg through 9.0.2 contains an off-by-one heap overflow vulnerability in get_exponent_dynamic() in libavcodec/nellymoserenc.c that allows writing one element past the opt and path allocations. Attackers can supply crafted audio to applications encoding Nellymoser with trellis enabled, causing idx to equal OPT_SIZE and overwrite adjacent heap memory.

FFmpeg through 9.0.2 VP9 CBS Superframe Integer Overflow Out-of-Bounds Read

FFmpeg through 9.0.2 contains an integer overflow in cbs_vp9_split_fragment() in libavcodec/cbs_vp9.c that wraps the superframe size check on 32-bit builds. Attackers can supply a crafted VP9 packet with a forged superframe index containing near-2^32 frame sizes, causing out-of-bounds reads that crash 32-bit applications.

FFmpeg 7.1 through 9.0.2 Heap Out-of-Bounds Write via Vulkan Slice Buffer Sizing

FFmpeg 7.1 through 9.0.2 contains an integer overflow in ff_vk_decode_add_slice() in libavcodec/vulkan_decode.c that miscalculates the Vulkan hwaccel bitstream buffer size. Attackers can supply a crafted stream with over 2 GiB of slice data per frame, causing memcpy() to write past a smaller pooled host-mapped buffer.

FFmpeg through 9.0.2 Heap Buffer Overflow via hap_parse_frame_header()

FFmpeg through 9.0.2 contains an integer overflow vulnerability in hap_parse_frame_header() in libavcodec/hapdec.c that allows attackers to trigger a heap buffer overflow on 32-bit builds. Attackers can craft Hap video frames with Snappy length prefixes that wrap tex_size, causing decompress_chunks_thread() to write outside tex_buf and crash the application or potentially execute code.

FFmpeg through 9.0.2 Heap Buffer Overflow via PSD Decoder RLE Path

FFmpeg through 9.0.2 contains a heap buffer overflow vulnerability in the PSD decoder in libavcodec/psd.c that allows attackers to corrupt heap memory on 32-bit builds by supplying a crafted PSD image. Attackers can choose dimensions and channel counts whose product exceeds 4 GB, truncating the av_malloc allocation size so decode_rle() writes attacker-controlled data past the buffer, causing crashes or possible code execution.

FFmpeg through 9.0.2 Heap Out-of-Bounds Read via LCL/ZLIB Multithread Decoding

FFmpeg through 9.0.2 contains an integer underflow in decode_frame() in libavcodec/lcldec.c that allows attackers to trigger a heap out-of-bounds read via short ZLIB packets with FLAG_MULTITHREAD. Attackers can supply a crafted AVI or MKV file with an LCL video stream whose packet is shorter than 8 bytes, bypassing length clamping to crash the decoding application.

FFmpeg through 9.0.2 Integer Overflow in OpenEXR Decoder Tile Count

FFmpeg through 9.0.2 contains an integer overflow vulnerability in the OpenEXR decoder's decode_frame() in libavcodec/exr.c that miscalculates the tiled block count. Attackers can supply a crafted tiled OpenEXR image with large dimensions and small tiles to skip decoding and disclose uninitialized memory or stale frame data.

Android WAP Push Denial of Service via Integer Overflow

In decodeWapPdu of WapPushOverSms.java, there is a possible out of bounds read due to an integer overflow. This could lead to a remote denial of service with no additional execution privileges needed. User interaction is not needed for exploitation.

Hickory DNS from 0.26.0 before 0.26.2 Panic via TSIG RDATA Decoding

Hickory DNS from 0.26.0 before 0.26.2 contains an integer underflow vulnerability in TSIG RDATA decoding that allows remote attackers to trigger a panic via malformed records. Attackers can send a crafted TSIG record in DNS wire format to cause unchecked subtraction underflow, crashing builds with overflow checks enabled and causing denial of service.

Kore before 4.3.0 Integer Underflow Memory Exhaustion via http_header_recv()

Kore before 4.3.0 contains an integer underflow vulnerability in HTTP request body handling that allows unauthenticated attackers to bypass http_body_max by sending more body bytes than declared. Attackers can send oversized first segments over many concurrent POST, PUT or DELETE connections, wrapping content_length to grow buffers unbounded and exhaust worker memory.

In rw_ci_data_cback of rw_ci.cc, there is a possible memory safety issue due to integer underflow. This could lead to remote information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation.

Libx11: integer overflow in xcreateimage() leading to a heap overflow

A vulnerability was found in libX11 due to an integer overflow within the XCreateImage() function. This flaw allows a local user to trigger an integer overflow and execute arbitrary code with elevated privileges.

Ghostscript: integer overflow in pcl/pl/plfont.c:418 in pl_glyph_name

An integer overflow flaw was found in pcl/pl/plfont.c:418 in pl_glyph_name in ghostscript. This issue may allow a local attacker to cause a denial of service via transforming a crafted PCL file to PDF format.

Kernel: netfilter: potential slab-out-of-bound access due to integer underflow

An array indexing vulnerability was found in the netfilter subsystem of the Linux kernel. A missing macro could lead to a miscalculation of the `h->nets` array offset, providing attackers with the primitive to arbitrarily increment/decrement a memory buffer out-of-bound. This issue may allow a local user to crash the system or potentially escalate their privileges on the system.
