CVE-2013-5933
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedStack-based buffer overflow in the sub_E110 function in init in a certain configuration of Android 2.3.7 on the Motorola Defy XT phone for Republic Wireless allows local users to gain privileges or cause a denial of service (memory corruption) by writing a long string to the /dev/socket/init_runit socket that is inconsistent with a certain length value that was previously written to this socket.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceStack-based buffer overflow in the sub_E110 function in the init process on Android 2.3.7 for the Motorola Defy XT (Republic Wireless). The vulnerability exists in socket handling for /dev/socket/init_runit where a length value written to the socket is inconsistent with the actual string data length, allowing local privilege escalation or memory corruption.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the device modelCheck the device model via 'getprop ro.product.device' or 'getprop ro.product.name' in a shell or ADBAffected if The device is NOT a Motorola Defy XT (the device must be exactly Defy XT to be affected)
-
Identify the Android versionCheck Android version via 'getprop ro.build.version.release' in a shell or ADBAffected if The Android version is NOT 2.3.7 (version must be exactly 2.3.7 to be affected)
-
Verify the vulnerable socket existsCheck if /dev/socket/init_runit exists using 'ls -la /dev/socket/init_runit' in a shell or ADBAffected if The socket /dev/socket/init_runit does NOT exist (the vulnerability only exists when this socket is present)
-
Confirm Republic Wireless configurationCheck the carrier or operator via 'getprop gsm.operator.alpha' or 'getprop ro.carrier' in a shell or ADBAffected if The device is NOT on Republic Wireless network (this is a Republic Wireless specific configuration)
A user is affected ONLY if the device is a Motorola Defy XT, running Android 2.3.7, with the /dev/socket/init_runit socket present, on the Republic Wireless network.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataThis is a device-specific vulnerability affecting a narrow configuration (Motorola Defy XT on Republic Wireless with Android 2.3.7). Primary mitigation is to avoid using this specific device/configuration or obtain and apply an OEM patch if available.
