CVE-2021-44490
Using crafted input, attackers can cause a calculation of the size of calls to memset in op_fnj3 in sr_port/op_fnj3.c to result in an extremely large value in order to cause a segmentation fault and crash the application.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.02%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
An issue was discovered in YottaDB through r1.32 and V7.0-000. Using crafted input, attackers can cause a calculation of the size of calls to memset in op_fnj3 in sr_port/op_fnj3.c to result in an extremely large value in order to cause a segmentation fault and crash the application. This is a "- (digs < 1 ? 1 : digs)" subtraction.
