Arch Linux Security Advisory ASA-202010-10 ========================================== Severity: High Date : 2020-10-20 CVE-ID : CVE-2020-15999 Package : freetype2 Type : arbitrary code execution Remote : Yes Link : https://security.archlinux.org/AVG-1254 Summary ======= The package freetype2 before version 2.10.4-1 is vulnerable to arbitrary code execution. Resolution ========== Upgrade to 2.10.4-1. # pacman -Syu "freetype2>=2.10.4-1" The problem has been fixed upstream in version 2.10.4. Workaround ========== None. Description =========== A heap buffer overflow has been found in freetype2 before 2.10.4. Malformed TTF files with PNG sbit glyphs can cause a heap buffer overflow in Load_SBit_Png as libpng uses the original 32-bit values, which are saved in png_struct. If the original width and/or height are greater than 65535, the allocated buffer won't be able to fit the bitmap. Impact ====== A remote user can serve malformed TTF files that can cause arbitrary code execution on the affected host.
