CVE-2026-47714

A flaw was found in libheif, a HEIF and AVIF file format decoder and encoder. An integer overflow vulnerability exists in the inline mask parsing code, where the product of image width and height can exceed the maximum 32-bit unsigned integer value. This leads to an undersized buffer allocation,...

CVE-2026-47714

libheif is a HEIF and AVIF file format decoder and encoder. In versions 1.21.2 and prior, the inline mask parsing code in libheif/region.cc contains an integer overflow. Both width and height are unsigned int 32-bit values parsed from the HEIF file. Their product can exceed UINT32MAX, wrapping to...

CVE-2026-45191

Net::CIDR::Lite (Perl) is affected in versions before 0.24. The flaw is in CIDR mask handling: extraneous zero characters in masks are not properly validated, causing /00 and /01 (and other zero-padded forms) to pass validation and be parsed to the same prefix as the unpadded value, potentially a...

CVE-2026-45191

Net::CIDR::Lite versions before 0.24 for Perl does not properly consider extraneous zero characters in CIDR mask values, which may allow IP ACL bypass. Mask forms like "/00" and "/01" pass validation and parse to the same prefix as their unpadded value. See also CVE-2026-45190...
