CVE-2009-4012
Multiple integer overflows in LibThai before 0.1.13 might allow context-dependent attackers to execute arbitrary code via long strings that trigger heap-based buffer overflows, related to (1) thbrk/thbrk.c and (2) thwbrk/thwbrk.c.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (4.41%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
