Linux Debian vulnerability analysis and mitigation
Overview
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 fincr in srport/f_incr.c and cause a crash due to a NULL pointer dereference (NVD).
Technical details
The vulnerability is classified as a NULL Pointer Dereference (CWE-476) issue. The CVSS v3.1 base score is 7.5 HIGH with a vector of CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H. The vulnerability exists in the function fincr in srport/f_incr.c where improper type initialization can lead to a NULL pointer dereference (NVD).
Impact
When successfully exploited, this vulnerability can cause the application to crash due to the NULL pointer dereference, leading to a denial of service condition. The vulnerability affects availability but does not impact confidentiality or integrity (NVD).
Mitigation and workarounds
The vulnerability has been fixed in later versions of both YottaDB and FIS GT.M. Users should upgrade to versions newer than YottaDB r1.32 and GT.M V7.0-000. The fix is included in GT.M V7.0-002 release (GT.M Release Notes).
