CVE-2021-44490 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. 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. EPSS estimates a 0.97% chance of exploitation in the next 30 days.

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.
