This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.\n\n NOTE: This CVE affects only End Of Life (EOL) software components. The vendor, Microsoft, has indicated there will be no future updates nor support provided upon inquiry.", "affected": [ { "vendor": "Microsoft", "product": ".NET 6.0", "platforms": [ "Windows", "MacOS", "Linux" ], "versions": [ { "version": "6.0.0", "status": "affected", "versionType": "custom", "lessThan": "6.0.36" } ] }, { "vendor": "Microsoft", "product": "Microsoft.NetCore.App.Runtime.linux-arm", "packageName": "Microsoft.AspNetCore.Identity", "platforms": [ "Windows", "Linux", "MacOS" ], "defaultStatus": "unaffected", "versions": [ { "version": ">=6.0.0", "status": "affected", "versionType": "semver", "lessThanOrEqual": "6.0.36" } ] }, { "vendor": "Microsoft", "product": "Microsoft.NetCore.App.Runtime.linux-arm64", "packageName": "Microsoft.AspNetCore.Identity", "platforms": [ "Windows", "Linux", "MacOS" ], "defaultStatus": "unaffected", "versions": [ { "version": ">=6.0.0", "status": "affected", "versionType": "semver", "lessThanOrEqual": "6.0.36" } ] }, { "vendor": "Microsoft", "product": "Microsoft.NetCore.App.Runtime.linux-musl-arm", "packageName": "Microsoft.AspNetCore.Identity", "platforms": [ "Windows", "Linux", "MacOS" ], "defaultStatus": "unaffected", "versions": [ { "version": ">=6.0.0", "status": "affected", "versionType": "semver", "lessThanOrEqual": "6.0.36" } ] }, { "vendor": "Microsoft", "product": "Microsoft.NetCore.App.Runtime.linux-musl-arm64", "packageName": "Microsoft.AspNetCore.Identity", "platforms": [ "Windows", "Linux", "MacOS" ], "defaultStatus": "unaffected", "versions": [ { "version": ">=6.0.0", "status": "affected", "versionType": "semver", "lessThanOrEqual": "6.0.36" } ] }, { "vendor": "Microsoft", "product": "Microsoft.NetCore.App.Runtime.linux-musl-x64", "packageName": "Microsoft.AspNetCore.Identity", "platforms": [ "Windows", "Linux", "MacOS" ], "defaultStatus": "unaffected", "versions": [ { "version": ">=6.0.0", "status": "affected", "versionType": "semver", "lessThanOrEqual": "6.0.36" } ] }, { "vendor": "Microsoft", "product": "Microsoft.NetCore.App.Runtime.linux-x64", "packageName": "Microsoft.AspNetCore.Identity", "platforms": [ "Windows", "Linux", "MacOS" ], "defaultStatus": "unaffected", "versions": [ { "version": ">=6.0.0", "status": "affected", "versionType": "semver", "lessThanOrEqual": "6.0.36" } ] }, { "vendor": "Microsoft", "product": "Microsoft.NetCore.App.Runtime.osx-arm64", "packageName": "Microsoft.AspNetCore.Identity", "platforms": [ "Windows", "Linux", "MacOS" ], "defaultStatus": "unaffected", "versions": [ { "version": ">=6.0.0", "status": "affected", "versionType": "semver", "lessThanOrEqual": "6.0.36" } ] }, { "vendor": "Microsoft", "product": "Microsoft.NetCore.App.Runtime.osx-x64", "packageName": "Microsoft.AspNetCore.Identity", "platforms": [ "Windows", "Linux", "MacOS" ], "defaultStatus": "unaffected", "versions": [ { "version": ">=6.0.0", "status": "affected", "versionType": "semver", "lessThanOrEqual": "6.0.36" } ] }, { "vendor": "Microsoft", "product": "Microsoft.NetCore.App.Runtime.win-arm", "packageName": "Microsoft.AspNetCore.Identity", "platforms": [ "Windows", "Linux", "MacOS" ], "defaultStatus": "unaffected", "versions": [ { "version": ">=6.0.0", "status": "affected", "versionType": "semver", "lessThanOrEqual": "6.0.36" } ] }, { "vendor": "Microsoft", "product": "Microsoft.NetCore.App.Runtime.win-arm64", "packageName": "Microsoft.AspNetCore.Identity", "platforms": [ "Windows", "Linux", "MacOS" ], "defaultStatus": "unaffected", "versions": [ { "version": ">=6.0.0", "status": "affected", "versionType": "semver", "lessThanOrEqual": "6.0.36" } ] }, { "vendor": "Microsoft", "product": "Microsoft.NetCore.App.Runtime.win-x64", "packageName": "Microsoft.AspNetCore.Identity", "platforms": [ "Windows", "Linux", "MacOS" ], "defaultStatus": "unaffected", "versions": [ { "version": ">=6.0.0", "status": "affected", "versionType": "semver", "lessThanOrEqual": "6.0.36" } ] }, { "vendor": "Microsoft", "product": "Microsoft.NetCore.App.Runtime.win-x86", "packageName": "Microsoft.AspNetCore.Identity", "platforms": [ "Windows", "Linux", "MacOS" ], "defaultStatus": "unaffected", "versions": [ { "version": ">=6.0.0", "status": "affected", "versionType": "semver", "lessThanOrEqual": "6.0.36" } ] } ] } } }
