%55

Short explanation

Pillow contains a vulnerability where an invalid glyph pointer can be freed during FreeType glyph rendering when a stroker is active [S0].

Why does it matter?

Attackers can exploit this issue by supplying malformed fonts to trigger process crashes or memory corruption [S0].

What should be done?

Follow vendor advisories to apply available updates [S0]

Chain of evidence and sources2 verified claims

Pillow, Python görüntüleme kütüphanesidir ve 10.0.0 ile 13.0.0 sürümleri arasında bu zafiyetten etkilenmektedir [S0].

Show the technical text from the sources

Pillow is a Python imaging library. From 10.0.0 until 13.0.0, Pillow can free an invalid glyph pointer during FreeType rendering with an active stroker. If FT_Load_Glyph fails, cleanup may call FT_Done_Glyph on an uninitialized or stale glyph variable. An attacker can supply a malformed font as untrusted bytes to an application that draws text with a nonzero stroke width, forcing the glyph-load failure path. This can corrupt memory or crash the process. This issue is fixed in version 13.0.0.
