A vulnerability in sendmail could allow a local attacker to obtain sensitive information.
| Package | Arch | Vulnerable | Unaffected |
|---|---|---|---|
| mail-mta/sendmail | * | < 8.14.9 | >= 8.14.9 |
sendmail is a widely-used Mail Transport Agent (MTA).
The sm_close_on_exec function in conf.c has arguments in the wrong order.
A local attacker could get access to unintended high-numbered file descriptors via a specially crafted program.
There is no known workaround at this time.
All sendmail users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=mail-mta/sendmail-8.14.9"
An error in the hostname matching in sendmail might enable remote attackers to conduct man-in-the-middle attacks.
| Package | Arch | Vulnerable | Unaffected |
|---|---|---|---|
| mail-mta/sendmail | * | < 8.14.4 | >= 8.14.4 |
sendmail is a widely-used Mail Transport Agent (MTA).
A vulnerability has been discovered in sendmail. Please review the CVE identifier referenced below for details.
A remote attacker might employ a specially crafted certificate to conduct man-in-the-middle attacks on SSL connections made using sendmail.
There is no known workaround at this time.
All sendmail users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=mail-mta/sendmail-8.14.4"
Faulty multipart MIME messages can cause forked Sendmail processes to crash.
| Package | Arch | Vulnerable | Unaffected |
|---|---|---|---|
| mail-mta/sendmail | * | < 8.13.6-r1 | >= 8.13.6-r1 |
Sendmail is a popular mail transfer agent (MTA).
Frank Sheiness discovered that the mime8to7() function can recurse endlessly during the decoding of multipart MIME messages until the stack of the process is filled and the process crashes.
By sending specially crafted multipart MIME messages, a remote attacker can cause a subprocess forked by Sendmail to crash. If Sendmail is not set to use a randomized queue processing, the attack will effectively halt the delivery of queued mails as well as the malformed one, incoming mail delivered interactively is not affected. Additionally, on systems where core dumps with an individual naming scheme (like "core.pid") are enabled, a filesystem may fill up with core dumps. Core dumps are disabled by default in Gentoo.
The Sendmail 8.13.7 release information offers some workarounds, please see the Reference below. Note that the issue has actually been fixed in the 8.13.6-r1 ebuild.
All Sendmail users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=mail-mta/sendmail-8.13.6-r1"
Sendmail is vulnerable to a race condition which could lead to the execution of arbitrary code with sendmail privileges.
| Package | Arch | Vulnerable | Unaffected |
|---|---|---|---|
| mail-mta/sendmail | * | < 8.13.6 | >= 8.13.6 |
Sendmail is a popular mail transfer agent (MTA).
ISS discovered that Sendmail is vulnerable to a race condition in the handling of asynchronous signals.
An attacker could exploit this via certain crafted timing conditions.
There is no known workaround at this time.
All Sendmail users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=mail-mta/sendmail-8.13.6"
