1. Bulletins Topics
Sun announces the release of patches for Solaris(tm) 8, 7, 2.6,
2.5.1, and 2.5 (SunOS(tm) 5.8, 5.7, 5.6, 5.5.1, and 5.5) which
relate to an in.ftpd vulnerability reported in CERT CA-2001-07.
Sun recommends that you install the patches listed in section 4
immediately on systems running SunOS 5.8, 5.7, 5.6, 5.5.1, and
5.5 which use in.ftpd.
2. Who is Affected
Vulnerable: SunOS 5.8, 5.8_x86, 5.7, 5.7_x86, 5.6,
5.6_x86, 5.5.1, 5.5.1_x86, 5.5, 5.5_x86
3. Understanding the Vulnerability
The in.ftpd daemon is the Internet File Transfer Protocol (FTP)
server process. The FTP server process interprets file names
according to the "globbing" conventions used by sh(1). CERT
Advisory CA-2001-07 describes a vulnerability in some of the
"globbing" routines which incorrectly manage buffers and may
allow remote users to execute arbitrary code on the FTP server.
The issue was discovered by COVERT Labs at PGP Security who
describe their findings at:
http://www.pgp.com/research/covert/advisories/048.asp
CERT Advisory CA-2001-07 is available from:
http://www.cert.org/advisories/CA-2001-07.html
