Descriptions
expand.c in Exim before 4.83 expands mathematical comparisons twice, which allows local users to gain privileges and execute arbitrary commands via a crafted lookup value.
expand.c en Exim anterior a 4.83 expande las comparaciones matemáticas dos veces, lo que permite a usuarios locales ganar privilegios y ejecutar comandos arbitrarios a través de un valor lookup maniulado.
It was discovered that Exim incorrectly filtered environment variables when used with the perl_startup configuration option. If the perl_startup option was enabled, a local attacker could use this issue to escalate their privileges to the root user. This issue has been fixed by having Exim clean the complete execution environment by default on startup, including any subprocesses such as transports that call other programs. This change in behaviour may break existing installations and can be adjusted by using two new configuration options, keep_environment and add_environment. Various other issues were also addressed.
