Severity: Normal
Title: Multiple format string vulnerabilities in cadaver
Date: April 19, 2004
Bugs: #47799
ID: 200404-14

---

Synopsis

There are multiple format string vulnerabilities in the neon
library used in cadaver, possibly leading to execution of arbitrary
code when connected to a malicious server.

Background

According to http://www.webdav.org/cadaver,
cadaver is a command-line WebDAV client for Unix. It supports file
upload, download, on-screen display, namespace operations
(move/copy), collection creation and deletion, and locking
operations.

Affected packages

Description

Cadaver code includes the neon library, which in versions 0.24.4
and previous is vulnerable to multiple format string attacks. The
latest version of cadaver uses version 0.24.5 of the neon library,
which makes it immune to this vulnerability.

Impact

When using cadaver to connect to an untrusted WebDAV server,
this vulnerability can allow a malicious remote server to execute
arbitrary code on the client with the rights of the user using
cadaver.

Workaround

A workaround is not currently known for this issue. All users
are advised to upgrade to the latest version of the affected
package.

Resolution

cadaver users should upgrade to version 0.22.1 or later:

    # emerge sync
    # emerge -pv ">=net-misc/cadaver-0.22.1"
    # emerge ">=net-misc/cadaver-0.22.1"

Severity: Low
Title: XChat 2.0.x SOCKS5 Vulnerability
Date: April 19, 2004 Bugs: #46856
ID: 200404-15

---

Synopsis

XChat is vulnerable to a stack overflow that may allow a remote
attacker to run arbitrary code.

Background

XChat is a multiplatform IRC client.

Affected packages

Description

The SOCKS 5 proxy code in XChat is vulnerable to a remote
exploit. Users would have to be using XChat through a SOCKS 5
server, enable SOCKS 5 traversal which is disabled by default and
also connect to an attacker’s custom proxy server.

Impact

This vulnerability may allow an attacker to run arbitrary code
within the context of the user ID of the XChat client.

Workaround

A workaround is not currently known for this issue. All users
are advised to upgrade to the latest version of the affected
package.

Resolution

All XChat users should upgrade to the latest stable version:

# emerge sync

# emerge -pv “>=net-irc/xchat-2.0.8-r1” # emerge
“>=net-irc/xchat-2.0.8-r1”

Note that users of the gtk1 version of xchat (1.8.*) should
upgrade to xchat-1.8.11-r1:

    # emerge sync
    # emerge -pv "=net-irc/xchat-1.8.11-r1"
    # emerge "=net-irc/xchat-1.8.11-r1"

Severity: High
Title: Multiple new security vulnerabilities in monit
Date: April 19, 2004
Bugs: #47631 ID: 200404-16

---

Synopsis

Two new vulnerabilities have been found in the HTTP interface of
monit, possibly leading to denial of service or execution of
arbitrary code.

Background

Monit is a system administration utility that allows management
and monitoring of processes, files, directories and devices on a
Unix system.

Affected packages

Description

Monit has several vulnerabilities in its HTTP interface : a
buffer overflow vulnerability in the authentication handling code
and a off-by-one error in the POST method handling code.

Impact

An attacker may exploit the off-by-one error to crash the Monit
daemon and create a denial of service condition, or cause a buffer
overflow that would allow arbitrary code to be executed with root
privileges.

Workaround

A workaround is not currently known for this issue. All users
are advised to upgrade to the latest version of the affected
package.

Resolution

Monit users should upgrade to version 4.2.1 or later:

    # emerge sync
    # emerge -pv ">=app-admin/monit-4.2.1"
    # emerge ">=app-admin/monit-4.2.1"
