DSA-248-1 hypermail -- buffer overflows
- Date Reported:
- 31 Jan 2003
- Affected Packages:
- hypermail
- Vulnerable:
- Yes
- Security database references:
- In the Bugtraq database (at SecurityFocus): BugTraq ID 6689, BugTraq ID 6690.
In Mitre's CVE dictionary: CVE-2003-0057. - More information:
-
Ulf Härnhammar discovered two problems in hypermail, a program to create HTML archives of mailing lists.
An attacker could craft a long filename for an attachment that would overflow two buffers when a certain option for interactive use was given, opening the possibility to inject arbitrary code. This code would then be executed under the user id hypermail runs as, mostly as a local user. Automatic and silent use of hypermail does not seem to be affected.
The CGI program mail, which is not installed by the Debian package, does a reverse look-up of the user's IP number and copies the resulting hostname into a fixed-size buffer. A specially crafted DNS reply could overflow this buffer, opening the program to an exploit.
For the stable distribution (woody) this problem has been fixed in version 2.1.3-2.0.
For the old stable distribution (potato) this problem has been fixed in version 2.0b25-1.1.
For the unstable distribution (sid) this problem has been fixed in version 2.1.6-1.
We recommend that you upgrade your hypermail packages.
