Bug 166440 - app-arch/{un,}rar- remotely exploitable stack based buffer overflow (CVE-2007-0855)
Bug#: 166440 Product:  Gentoo Security Version: unspecified Platform: All
OS/Version: Linux Status: RESOLVED Severity: normal Priority: P2
Resolution: FIXED Assigned To: security@gentoo.org Reported By: carlo@gentoo.org

Summary: app-arch/{un,}rar- remotely exploitable stack based buffer overflow (CVE-2007-0855)
Keywords:  
Status Whiteboard: A2 [glsa] Falco
Opened: 2007-02-11 23:40 0000
Description:   Opened: 2007-02-11 23:40 0000
Exploitation of the vulnerability could allow an attacker to execute arbitrary
code with the privileges of the user opening the file. Exploitation would
require that an attacker hosts a maliciously crafted document on a website and
entice users to visit the site. An attacker could also e-mail the malicious
document and use social engineering techniques to trick the e-mail recipient
into opening the document.

There are several mitigating factors for this vulnerability. Nearly all Windows
users will use the GUI based WinRAR to open archives, and it is not vulnerable.
If users are using the vulnerable command line based unrar, they still need to
interact with the program in order to trigger the vulnerability. They must
respond to the prompt asking for the password, after which the vulnerability
will be triggered. They do not need to enter a correct password, but they must
at least push the enter key.

this may be the wrong place to report, but i think there is a dependency to
glibc 2.4 missing

/lib/libc.so.6: version `GLIBC_2.4' not found (required by /opt/bin/rar)

i can only use sys-libs/glibc-2.3.6-r5

Portage 2.1.2-r9 (selinux/2005.1/x86/hardened, gcc-3.4.6, glibc-2.3.6-r5,
2.6.18-hardened i686)
