Base vector

AV:N/AC:M/Au:N/C:P/I:P/A:P

Name of the Vulnerable Software and Affected Versions libESMTP versions 1.0.3.r1 through 1.0.4

Description The issue arises from the match component function in smtp-tls.c, which incorrectly treats two strings as equal if one is a substring of the other. This allows remote attackers to spoof trusted certificates by crafting a subjectAltName.

Recommendations For libESMTP versions 1.0.3.r1 through 1.0.4, consider disabling the match component function until a patch is available to prevent remote attackers from spoofing trusted certificates.
