MGASA-2020-0389 - Updated freetype2 packages fix security vulnerability

Publication date: 20 Oct 2020
URL: https://advisories.mageia.org/MGASA-2020-0389.html
Type: security
Affected Mageia releases: 7
CVE: CVE-2020-15999

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. (CVE-2020-15999)
