CVE-2026-67306 FreeRDP before 3.29.0 Out-of-Bounds Read via Planar RLE

FreeRDP versions 3.28.0 and earlier contain an out-of-bounds read vulnerability in the RDP6 planar RLE bitmap decoder functions planardecompressplanerle and planardecompressplanerleonly in libfreerdp/codec/planar.c. Only the 1-byte control byte is bounds-checked; the subsequent 0–15...

libXfont2: PCF Font Parsing Heap Buffer Overflow

A flaw was found in libXfont2. A specially crafted PCF Portable Compiled Format font file, when processed by libXfont2, can lead to a buffer overflow. This occurs because the font parsing process does not properly validate the size of a bitmap buffer against the glyph metrics provided in the...

libXfont2: BitmapScaleBitmaps Integer Overflow Heap Buffer Overflow

A flaw was found in libXfont2. In the BitmapScaleBitmaps function, an integer overflow can occur when calculating the memory needed for font glyphs. This overflow leads to a heap buffer overflow, where a smaller-than-required memory buffer is allocated. A local attacker can exploit this by loadin...

CVE-2026-59941 Dompdf: Uncontrolled resource consumption based on declared BMP dimensions

Dompdf is an HTML to PDF converter for PHP. Versions 3.15 and prior accept a BMP image and generates a PDF-compatible PNG based only on its declared header dimensions and never bounds width × height before the image is converted through GD. A 58-byte BMP whose header declares e.g. 6000×6000 is...

CVE-2026-59941

CVE-2026-59941 (Dompdf) affects Dompdf (PHP HTML-to-PDF converter) up through version 3.15. The root cause is that a BMP image’s declared width/height in the header is trusted, leading to allocation of a full GD canvas (e.g., 6000×6000) even if pixel data is minimal. This enables a lightweight 16...
