Description

The resolveImplicitLevels function in common/ubidi.c in the Unicode Bidirectional Algorithm implementation in ICU4C in International Components for Unicode (ICU) before 55.1 uses an integer data type that is inconsistent with a header file, which allows remote attackers to cause a denial of service (incorrect malloc followed by invalid free) or possibly execute arbitrary code via crafted text.

Affected

Our own answer: ranges merged, affected separated from platform-only, with confidence and review flags.

macOS· Apple
95%
v ≤ 10.10.4
watchOS· Apple
95%
v ≤ 1.0.1
International Components for Unicode· Icu Project
95%
v < 55.1
Affected range stops below 55.1, so it looks safe — our inference, not a vendor statement
