Title: BSD Nvi Format String Vulnerability
Severity: MODERATE
Description:
Nvi is an implementation of the vi text editor.
English and multilingual versions of Nvi are prone to format string attacks. This is due to insufficient validation of externally supplied data. Specifically, the routine handling saved filenames does not escape format strings.
This issue has not been proven to be exploitable. However, a possibility exists that this condition may be exploited by an attacker to overwrite locations in memory, potentially allowing the attacker to execute arbitrary code on the host.
Affected Products:
- BSD nvi 1.79.0
- Debian Linux 2.2.0
- Debian Linux 2.2.0 68k
- Debian Linux 2.2.0 alpha
- Debian Linux 2.2.0 arm
- Debian Linux 2.2.0 powerpc
- Debian Linux 2.2.0 sparc
