Discussion

Eterm LibAST Library Local Buffer Overflow Vulnerability

Eterm LibAST library is prone to a local buffer-overflow vulnerability.

An attacker can trigger this issue by supplying a long filename through the '-X' option of Eterm. A successful attack can corrupt memory and facilitate arbitrary code execution with the privileges of the 'utmp' user.

LibAST versions 0.6.1 and prior are vulnerable to this issue.

Note that other applications using the affected library may be vulnerable as well.
