Description

Two vulnerabilities were reported in sendmail.

  • CAN-2003-0681 : A 'potential buffer overflow in ruleset parsing' for Sendmail 8.12.9, when using the nonstandard rulesets (1) recipient (2), final, or (3) mailer-specific envelope recipients, has unknown consequences.

  • CAN-2003-0694 :

    The prescan function in Sendmail 8.12.9 allows remote attackers to execute arbitrary code via buffer overflow attacks, as demonstrated using the parseaddr function in parseaddr.c.
