CVE-2026-55564 FreeRDP: Out-of-bounds read in glyph_cache_get via crafted glyph fragments

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.27.0, the glyphcacheget function in libfreerdp/cache/glyph.c checks whether index is greater than cache-number instead of greater than or equal to it. A malicious RDP server can use GLYPHFRAGMENTUSE replay in...

CVE-2026-44950

A flaw was found in the libXfont2 font-server client. This heap buffer overflow vulnerability allows a malicious font server to send specially crafted glyph data. The fsreadglyphs function fails to properly validate the total size of the incoming data, leading to an overwrite of memory beyond the...
