Pillow: TarIO negative size field causes infinite CPU-spin loop

Summary TarIO.init does not check that a tar header's size field is positive. A crafted header with a negative size makes it seek backward onto itself. This causes an infinite loop that uses 100% CPU and never returns. Details TarIO.init reads 512-byte tar headers one at a time, looking for a...

CVE-2026-109380 modern-tar 0.3.5 through 0.8.5 Memory Exhaustion via Malformed Octal Size Field

modern-tar 0.3.5 through 0.8.5 contains a memory exhaustion vulnerability that allows attackers to produce negative entry sizes via non-octal bytes parsed by readOctal. Attackers can supply a crafted, optionally gzip-compressed, archive to unpackTar that buffers chunks indefinitely, exhausting...

CVE-2026-107388: Memory Allocation with Excessive Size Value

music-metadata is a metadata parser for audio and video media files. Prior to 11.16.0, the ID3v2 parser trusts the syncsafe tag-size field and allocates the complete tag body before checking whether the input contains the declared bytes. A truncated file containing only an ID3v2 header can reques...

CVE-2026-97689

urllib3 is an HTTP client library for Python. From 1.10.3 until 2.8.0, the HTTPResponse.readchunked and HTTPResponse.stream methods can allocate unbounded memory because the streaming chunk parser buffers the chunk-size field until newline or EOF without a length bound. The trigger is that a...

CVE-2026-6103

phartarnumber parses the octal size field of a TAR header into a uint32t with no overflow check. The field is 11 octal digits wide and holds values up to 0x1FFFFFFFF, so a size above 0xFFFFFFFF silently wraps. The parser then skips the wrong number of data blocks and interprets attacker-controlle...

CVE-2026-88051 Tesseract: Heap out-of-bounds write in GenericVector<T>::read due to independent reserved/size_used_ fields

Tesseract is an open source OCR engine. In version 5.5.3 and earlier, the callback form of GenericVector::read in src/ccutil/genericvector.h reads the independent int32 fields reserved and sizeused from a .traineddata model without a cap or an invariant check. reservereserved allocates the backin...
