Two vulnerabilities were reported in sendmail.
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.
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.
For the stable distribution (woody) these problems have been fixed in
sendmail version 8.12.3-6.6 and sendmail-wide version
8.12.3+3.5Wbeta-5.5.
For the unstable distribution (sid) these problems have been fixed in
sendmail version 8.12.10-1.
We recommend that you update your sendmail package.
