CVE-2026-93313

A flaw was found in Poppler. This vulnerability, an integer overflow, occurs within the `JBIG2Stream::readCodeTableSeg` function when processing specially crafted JBIG2 image data. A remote attacker could exploit this by providing specially crafted input, which may lead to memory corruption. This could result in a denial of service (DoS) or potentially allow for information disclosure.
