CVE-2026-107224

Excelize is a Go language library for reading and writing Microsoft Excel spreadsheets. From 2.1.0 to 2.11.0, a Zip64 uncompressed size with the high bit set is converted from uint64 to a negative int64 before signed size-limit checks and allocation. ReadZipReader obtains UncompressedSize64 throu...

CVE-2026-107224

The Excelize Go library (versions 2.1.0 to 2.11.0 ) is vulnerable to a panic during workbook opening due to an integer overflow/wraparound . When a crafted Zip64 entry declares an uncompressed size between $2^{63}$ and $2^{64}-1$, the library converts the uint64 value into a negative int64. This ...

SUSE CVE-2026-45820

fflate through 0.8.2 is vulnerable to denial of service via an infinite loop in unzipSync. A crafted ZIP archive with a central directory entry declaring compressedsize=0xFFFFFFFF ZIP64 sentinel but missing the required ZIP64 extra field tag 0x0001 causes z64e to loop indefinitely due to...

libarchive: libarchive: Signed Integer Overflow in archive_write_zip_header

A signed integer overflow vulnerability was found in libarchive's ZIP writer. In the archivewritezipheader function in archivewritesetformatzip.c, when ZIP encryption is enabled and the entry file size is close to INT64MAX, the addition of the encryption overhead to the entry size overflows int64...
