Sendmail 8.8.8 - 8.12.7 Multiple Vulnerabilities (Bypass, OF)
Critical Nessus Plugin ID 11321
SynopsisThe remote host has an application that is affected by multiple vulnerabilities.
Descriptionsmrsh (supplied by Sendmail) is designed to prevent the execution of commands outside of the restricted environment. However, when commands are entered using either double pipes (||) or a mixture of dot and slash characters, a user may be able to bypass the checks performed by smrsh. This can lead to the execution of commands outside of the restricted environment.
In addition, a function in headers.c does not properly sanitize input supplied via the 'Address Field' causing an exploitable buffer overflow condition. However, Nessus has not checked for this.
SolutionUpgrade to Sendmail 8.12.8 or later.
