Buffer Over-read

A buffer over-read in Fortinet FortiOS versions 7.4.0 through 7.4.3, versions 7.2.0 through 7.2.7, and versions 7.0.0 through 7.0.14 may allow a remote unauthenticated attacker to crash the FGFM daemon via a specially crafted request, under rare conditions that are outside of the attacker's control.Show less

An issue was discovered in Insyde InsydeH2O kernel 5.2 before version 05.29.50, kernel 5.3 before version 05.38.50, kernel 5.4 before version 05.46.50, kernel 5.5 before version 05.54.50, kernel 5.6 before version 05.61.50, and kernel 5.7 before version 05.70.50. In VariableRuntimeDxe driver, SmmUpdateVariablePropertySmi () is a SMM callback function and it uses StrCmp () to compare variable names. This action may cause a buffer over-read.Show less

An issue was discovered in Insyde InsydeH2O kernel 5.2 before version 05.29.50, kernel 5.3 before version 05.38.50, kernel 5.4 before version 05.46.50, kernel 5.5 before version 05.54.50, kernel 5.6 before version 05.61.50, and kernel 5.7 before version 05.70.50. In VariableRuntimeDxe driver, VariableServicesSetVariable () can be called by gRT_>SetVariable () or the SmmSetSensitiveVariable () or SmmInternalSetVariable () from SMM. In VariableServicesSetVariable (), it uses StrSize () to get variable name size, uses StrLen () to get variable name length and uses StrCmp () to compare strings. These actions may cause a buffer over-read.Show less

In VariableRuntimeDxe driver, callback function SmmCreateVariableLockList () calls CreateVariableLockListInSmm (). In CreateVariableLockListInSmm (), it uses StrSize () to get variable name size and it could lead to a buffer over-read.Show less

Buffer over-read in PostgreSQL GB18030 encoding validation allows a database input provider to achieve temporary denial of service on platforms where a 1-byte over-read can elicit process termination. This affects the database server and also libpq. Versions before PostgreSQL 17.5, 16.9, 15.13, 14.18, and 13.21 are affected.Show less
