Summary:

Several security issues were fixed in FIS-GT.M.

Software Description:
- fis-gtm: database engine for large real-time transaction processing systems

Details:

It was discovered that FIS-GT.M could incorrectly dereference memory in
certain instances. An attacker could possibly use this issue to cause
FIS-GT.M to crash, resulting in a denial of service.
(CVE-2021-44492, CVE-2021-44498, CVE-2021-44508)

It was discovered that FIS-GT.M could perform a division by zero due to
a lack of input validation. An attacker could possibly use this issue to
cause FIS-GT.M to crash, resulting in a denial of service.
(CVE-2021-44500)

It was discovered that FIS-GT.M could be forced to allocate memory of a
chosen size through crafted input. An attacker could possibly use this
issue to exhaust the available memory of FIS-GT.M, leading to a crash
that would result in a denial of service. (CVE-2021-44502)

It was discovered that FIS-GT.M could be forced to read from uninitialized
memory due to a lack of input validation. An attacker could possibly use
this issue to cause FIS-GT.M to crash, resulting in a denial of service,
or execute arbitrary code. (CVE-2021-44506)

It was discovered that FIS-GT.M could crash due to an integer underflow.
An attacker could possibly use this issue to cause a denial of service.
