Name of the Vulnerable Software and Affected Versions BSD libc library (affected versions not specified)

Description The issue is related to improper bounds checking of the obuf variable in the link ntoa() function, which may allow an attacker to read or write from memory. The impact and severity depend on the method of exploit and how the library is used by applications. According to analysis, it is unlikely that applications exist that utilize link ntoa() in an exploitable manner, and there is no known proof of concept.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
