CVE-2021-44496:
An issue was discovered in FIS GT.M through V7.0-000 (related to the YottaDB code base). Using crafted input, an attacker can control the size variable and buffer that is passed to a call to memcpy. An attacker can use this to overwrite key data structures and gain control of the flow of execution.
CVE-2021-44504:
An issue was discovered in FIS GT.M through V7.0-000 (related to the YottaDB code base). Using crafted input, an attacker can cause a size variable, stored as an signed int, to equal an extremely large value, which is interpreted as a negative value during a check. This value is then used in a memcpy call on the stack, causing a memory segmentation fault.

CVE-2021-44492:
An issue was discovered in YottaDB through r1.32 and V7.0-000 and FIS GT.M through V7.0-000. Using crafted input, attackers can cause a type to be incorrectly initialized in the function f_incr in sr_port/f_incr.c and cause a crash due to a NULL pointer dereference.
CVE-2021-44493:
An issue was discovered in YottaDB through r1.32 and V7.0-000 and FIS GT.M through V7.0-000. Using crafted input, an attacker can cause a call to $Extract to force an signed integer holding the size of a buffer to take on a large negative number, which is then used as the length of a memcpy call that occurs on the stack, causing a buffer overflow.
CVE-2021-44494:
An issue was discovered in YottaDB through r1.32 and V7.0-000 and FIS GT.M through V7.0-000. Using crafted input, an attacker can cause calls to ZRead to crash due to a NULL pointer dereference.
CVE-2021-44495:
An issue was discovered in YottaDB through r1.32 and V7.0-000 and FIS GT.M through V7.0-000. Using crafted input, an attacker can cause a NULL pointer dereference after calls to ZPrint.
CVE-2021-44496:
An issue was discovered in FIS GT.M through V7.0-000 (related to the YottaDB code base). Using crafted input, an attacker can control the size variable and buffer that is passed to a call to memcpy. An attacker can use this to overwrite key data structures and gain control of the flow of execution.
CVE-2021-44497:
An issue was discovered in FIS GT.M through V7.0-000 (related to the YottaDB code base). Using crafted input, can cause the bounds of a for loop to be miscalculated, which leads to a use after free condition a pointer is pushed into previously free memory by the loop.
CVE-2021-44498:
An issue was discovered in FIS GT.M through V7.0-000 (related to the YottaDB code base). Using crafted input, attackers can cause a type to be incorrectly initialized in the function f_incr in sr_port/f_incr.c and cause a crash due to a NULL pointer dereference.
CVE-2021-44499:
An issue was discovered in FIS GT.M through V7.0-000 (related to the YottaDB code base). Using crafted input, an attacker can cause a call to $Extract to force an signed integer holding the size of a buffer to take on a large negative number, which is then used as the length of a memcpy call that occurs on the stack, causing a buffer overflow.
CVE-2021-44500:
An issue was discovered in FIS GT.M through V7.0-000 (related to the YottaDB code base). A lack of input validation in calls to eb_div in sr_port/eb_muldiv.c allows attackers to crash the application by performing a divide by zero.
CVE-2021-44501:
An issue was discovered in FIS GT.M through V7.0-000 (related to the YottaDB code base). Using crafted input, an attacker can cause calls to ZRead to crash due to a NULL pointer dereference.
CVE-2021-44502:
