Detailsinfo

A vulnerability was found in GNU ed up to 0.9. It has been declared as critical. Affected by this vulnerability is the function strip_escapes of the file signal.c. The manipulation with an unknown input leads to a memory corruption vulnerability. The CWE definition for the vulnerability is CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

Heap-based buffer overflow in the strip_escapes function in signal.c in GNU ed before 1.0 allows context-dependent or user-assisted attackers to execute arbitrary code via a long filename. NOTE: since ed itself does not typically run with special privileges, this issue only crosses privilege boundaries when ed is invoked as a third-party component.
