Mandrake Linux Security Advisory : procmail (MDKSA-2001:085)

In older versions of procmail, it is possible to crash procmail by sending it certain signals. If procmail is installed setuid, this could be exploited to gain unauthorized privilege. This problem is fixed in unstable version 3.20 and stable version 3.15.2. %NASLMINLEVEL 70300 C Tenable Network...

Mandrake Linux Security Advisory : groff (MDKSA-2002:012)

zen-parse discovered an exploitable buffer overflow in groff's preprocessor. If groff is invoked using the LPRng printing system, an attacker can gain rights as the 'lp' user. Likewise, this may be remotely exploitable if lpd is running and remotely accessible and the attacker knows the name of t...

Mandrake Linux Security Advisory : gzip (MDKSA-2002:011)

There are two problems with the gzip archiving program; the first is a crash when an input file name is over 1020 characters, and the second is a buffer overflow that could be exploited if gzip is run on a server such as an FTP server. The patch applied is from the gzip developers and the problem...

Mandrake Linux Security Advisory : tar (MDKSA-2002:066)

A directory traversal vulnerability was discovered in GNU tar version 1.13.25 and earlier that allows attackers to overwrite arbitrary files during extraction of the archive by using a '..' dot dot in an extracted filename. %NASLMINLEVEL 70300 C Tenable Network Security, Inc. The descriptive text...

Mandrake Linux Security Advisory : mod_ssl (MDKSA-2002:020)

Ed Moyle discovered a buffer overflow in modssl's session caching mechanisms that use shared memory and dbm. This could potentially be triggered by sending a very long client certificate to the server. %NASLMINLEVEL 70300 C Tenable Network Security, Inc. The descriptive text and package checks in...

Mandrake Linux Security Advisory : kernel (MDKSA-2003:038-1)

A bug in the kernel module loader code could allow a local user to gain root privileges. This is done by a local user using ptrace and attaching to a modprobe process that is spawned if the user triggers the loading of a kernel module. A temporary workaround can be used to defend against this fla...

Mandrake Linux Security Advisory : libpng (MDKSA-2003:008)

A buffer overflow vulnerability was discovered in libpng due to a wrong calculation of some loop offset values. This buffer overflow can lead to Denial of Service or even remote compromise. After the upgrade, all applications that use libpng should be restarted. Many applications are linked to...

Mandrake Linux Security Advisory : cdrecord (MDKSA-2003:058-1)

A vulnerability in cdrecord was discovered that can be used to obtain root access because Mandrake Linux ships with the cdrecord binary suid root and sgid cdwriter. Updated packages are provided that fix this vulnerability. You may also elect to remove the suid and sgid bits from cdrecord manuall...

Mandrake Linux Security Advisory : ipsec-tools (MDKSA-2004:027)

A very serious security flaw was discovered by Ralf Spenneberg in racoon, the IKE daemon of the KAME-tools. Racoon does not very the RSA signature during phase one of a connection using either main or aggressive mode. Only the certificate of the client is verified, the certificate is not used to...

Mandrake Linux Security Advisory : sendmail (MDKSA-2001:075)

An input validation error exists in sendmail that may allow local users to write arbitrary data to process memory. This could possibly allow the execute of code or commands with elevated privileges and may also allow a local attacker to gain access to the root account. %NASLMINLEVEL 70300 C Tenab...

Mandrake Linux Security Advisory : krb5 (MDKSA-2003:021)

A vulnerability was discovered in the Kerberos FTP client. When the client retrieves a file that has a filename beginning with a pipe character, the FTP client will pass that filename to the command shell in a system call. This could allow a malicious remote FTP server to write to files outside o...

Mandrake Linux Security Advisory : mod_ssl (MDKSA-2004:054)

A stack-based buffer overflow exists in the sslutiluuencodebinary function in sslenginekernel.c in modssl for Apache 1.3.x. When modssl is configured to trust the issuing CA, a remote attacker may be able to execute arbitrary code via a client certificate with a long subject DN. The provided...

Mandrake Linux Security Advisory : lftp (MDKSA-2003:116)

A buffer overflow vulnerability was discovered by Ulf Harnhammar in the lftp FTP client when connecting to a web server using HTTP or HTTPS and using the 'ls' or 'rels' command on specially prepared directory. This vulnerability exists in lftp versions 2.3.0 through 2.6.9 and is corrected upstrea...

Mandrake Linux Security Advisory : krb5 (MDKSA-2002:057)

The network authentication system in Kerberos 5 contains an RPC library that includes an XDR decoder derived from Sun's RPC implementation. This implemenation is vulnerable to a heap overflow. With Kerberos, it is believed that an attacker would need to be able to successfully authenticate to...

Mandrake Linux Security Advisory : gtkhtml (MDKSA-2003:093)

Alan Cox discovered that certain malformed messages could cause the Evolution mail component to crash due to a NULL pointer dereference in the GtkHTML library, versions prior to 1.1.0. The updated package provides a patched version of GtkHTML; versions of Mandrake Linux more recent than 9.0 do no...

Mandrake Linux Security Advisory : screen (MDKSA-2003:113)

A vulnerability was discovered and fixed in screen by Timo Sirainen who found an exploitable buffer overflow that allowed privilege escalation. This vulnerability also has the potential to allow attackers to gain control of another user's screen session. The ability to exploit is not trivial and...

Mandrake Linux Security Advisory : kdelibs (MDKSA-2004:047)

A vulnerability in the Opera web browser was identified by iDEFENSE; the same type of vulnerability exists in KDE. The telnet, rlogin, ssh, and mailto URI handlers do not check for '-' at the beginning of the hostname passed, which makes it possible to pass an option to the programs started by th...

Mandrake Linux Security Advisory : cvs (MDKSA-2004:028)

Sebastian Krahmer from the SUSE security team discovered a remotely exploitable vulnerability in the CVS client. When doing a cvs checkout or update over a network, the client accepts absolute pathnames in the RCS diff files. A maliciously configured server could then create any file with content...

Mandrake Linux Security Advisory : mc (MDKSA-2004:007)

A buffer overflow was discovered in mc's virtual filesystem code. This vulnerability could allow remote attackers to execute arbitrary code during symlink conversion. The updated packages have been patched to correct the problem. %NASLMINLEVEL 70300 C Tenable Network Security, Inc. The descriptiv...

Mandrake Linux Security Advisory : kdelibs (MDKSA-2003:079)

A vulnerability in Konqueror was discovered where it could inadvertently send authentication credentials to websites other than the intended site in clear text via the HTTP-referer header when authentication credentials are passed as part of a URL in the form http://user:password@host/. The...
