Summary
libXfont2 security update
Details

libXfont provides the core of the legacy X11 font system, handling the index files (fonts.dir, fonts.alias, fonts.scale), the various font file formats, and rasterizing them. contains runtime library.

Security Fix(es):

A heap buffer overflow in BitmapScaleBitmaps in libXfont2 before 2.0.8 due to an overflowing 32bit size could be used by attackers able to access the X Server to execute code within the X server context.(CVE-2026-56001)

A heap buffer overflow in pcfReadFont() due to missing glyph bounds checking in libXfont2 before 2.0.8 allows attackers authenticated as X client to execute code within the X server.(CVE-2026-56002)

A heap buffer overflow due to missing size checking in the property buffer when parsing PCF files in libXfont2 ComputeScaledProperties() before libXfont2 2.0.8 could be used by attackers using authenticated X clients to execute code within the X server.(CVE-2026-56003)
