Description:
Three vulnerabilities have been reported in Exim, which potentially can be exploited by malicious, local users to gain escalated privileges and by malicious people to compromise a vulnerable system.
1) A boundary error in the function "host_aton()" when handling IPv6 addresses may be exploited to cause a buffer overflow by supplying a specially crafted IPv6 address with more than 8 components to an unspecified command line option.
2) A boundary error in the function "spa_base64_to_bits()" when handling SPA authentication can be exploited to cause a buffer overflow.
Successful exploitation requires that SPA authentication is enabled.
3) A boundary error in the "dns_build_reverse()" function can be exploited to cause a buffer overflow by passing an overly long string via a command line option.
Successful exploitation may allow execution of arbitrary code with escalated privileges.
The vulnerabilities have been reported in version 4.43 and prior.
