cyrus-imapd: buffer overflow
| Package(s): | cyrus-imapd |
CVE #(s): | CVE-2009-2632
|
| Created: | September 8, 2009 |
Updated: | October 24, 2011 |
| Description: |
From the Debian advisory:
It was discovered that the SIEVE component of cyrus-imapd, a highly scalable
enterprise mail system, is vulnerable to a buffer overflow when processing
SIEVE scripts. Due to incorrect use of the sizeof() operator an attacker is
able to pass a negative length to snprintf() calls resulting in large positive
values due to integer conversion. This causes a buffer overflow which can be
used to elevate privileges to the cyrus system user. An attacker who is able
to install SIEVE scripts executed by the server is therefore able to read and
modify arbitrary email messages on the system. |
