python-pillow: Pillow: Denial of Service via crafted PCF font data

A flaw was found in Pillow, a Python imaging library. A remote attacker could exploit this vulnerability by providing specially crafted PCF font data. This data, when processed, can lead to excessive memory allocation because the library does not properly check for decompression bombs. The primar...

xorg: X11: xserver: X.org: glamor Font Atlas Heap Buffer Overflow

A flaw was found in the glamorfontget function of the xorg-x11-server. This vulnerability, a heap buffer overflow, occurs when the server processes a specially crafted PCF font file where individual glyph metrics exceed the declared maximum bounds. An authenticated X client can exploit this by...

libXfont2: computeProps Property Buffer Heap Buffer Overflow

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

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...

SUSE-SU-2026:22626-1 Security update for python-Pillow

This update for python-Pillow fixes the following issues - CVE-2026-42311: malicious PSD file processing can lead to arbitrary code execution bsc1270404. - CVE-2026-54059: crafted PCF font data can cause excessive memory allocation bsc1270409. - CVE-2026-54060: fonts can trigger excessive memory...

PYSEC-2026-2253

Pillow is a Python imaging library. Prior to 12.3.0, PIL/PcfFontFile.py loadbitmaps read glyph dimensions from the PCF METRICS section and passed them directly to Image.frombytes without calling Image.decompressionbombcheck, allowing crafted PCF font data to cause excessive memory allocation. Thi...
