Lifecycle Timeline
1DescriptionNVD
There is a vulnerability in htmldoc 1.9.16. In image_load_jpeg function image.cxx when it calls malloc,'img->width' and 'img->height' they are large enough to cause an integer overflow. So, the malloc function may return a heap blosmaller than the expected size, and it will cause a buffer overflow/Address boundary error in the jpeg_read_scanlines function.
AnalysisAI
There is a vulnerability in htmldoc 1.9.16. Rated medium severity (CVSS 5.5), this vulnerability is no authentication required, low attack complexity. Public exploit code available.
Technical ContextAI
This vulnerability is classified as Integer Overflow (CWE-190), which allows attackers to cause unexpected behavior through arithmetic overflow. There is a vulnerability in htmldoc 1.9.16. In image_load_jpeg function image.cxx when it calls malloc,'img->width' and 'img->height' they are large enough to cause an integer overflow. So, the malloc function may return a heap blosmaller than the expected size, and it will cause a buffer overflow/Address boundary error in the jpeg_read_scanlines function. Affected products include: Htmldoc Project Htmldoc, Debian Debian Linux.
RemediationAI
A vendor patch is available. Apply the latest security update as soon as possible. Validate arithmetic operations, use safe integer libraries, check bounds before allocation.
