computer vulnerability announce CVE-2007-4752

OpenSSH: obtaining X11 cookie

Synthesis of the vulnerability

An attacker, who can block the trusted X11 cookie copy operation, can obtain it.
Impacted products: Fedora, HP-UX, AIX, Mandriva Linux, Mandriva NF, OpenSSH, openSUSE, RHEL, Slackware, TurboLinux.
Severity: 1/4.
Consequences: data reading.
Provenance: intranet client.
Creation date: 05/09/2007.
Identifiers: BID-25628, c01271085, CERTA-2007-AVI-497, CERTA-2008-AVI-428, CVE-2007-4752, FEDORA-2007-715, HPSBUX02287, MDKSA-2007:236, RHSA-2008:0855-01, SSA:2007-255-01, SSRT071485, SUSE-SR:2007:022, TLSA-2009-15, VIGILANCE-VUL-7147.

Description of the vulnerability

When a client connects to the X11 server, it sends an authentication cookie (cookie A). Server checks this cookie and decides if it allows client to open a window.

In order to protect against a cookie theft, OpenSSH client generates a session cookie (cookie B) which will be only valid during the current session, then sends it to server. The remote OpenSSH server thus never obtains cookie A. When a program located on the remote computer opens a window, it sends cookie B, which is transformed by ssh client to ensure server receives cookie A.

However, if OpenSSH client fails to create cookie B, it sends cookie A to server.

An attacker who captured this cookie can therefore for example open windows from another session.

computer vulnerability CVE-2007-3849

Red Hat Enterprise Linux: changes not detected by AIDE

Synthesis of the vulnerability

Under Red Hat Enterprise Linux, the AIDE detection system does not detect file changes.
Impacted products: RHEL.
Severity: 2/4.
Consequences: data creation/edition, disguisement.
Provenance: user shell.
Creation date: 05/09/2007.
Identifiers: 236923, BID-25542, CVE-2007-3849, RHSA-2007:0539-01, VIGILANCE-VUL-7145.

Description of the vulnerability

The AIDE (Advanced Intrusion Detection Environment) software detects changes occurring on the file system. In order to do so, a database contains in particular hashes (md5, sha1, rmd160, tiger, haval, etc.) of files.

However, the compilation script of AIDE on Red Hat Enterprise Linux uses the WITH_LIBGCRYPT macro instead of WITH_GCRYPT. Hash features are thus not available, so file hashes stored in the database are always null. Changes are thus undetected.

A local attacker can therefore alter content of files without being detected by AIDE.

vulnerability note CVE-2007-4542 CVE-2007-4629

MapServer: several vulnerabilities

Synthesis of the vulnerability

An attacker can generate an overflow and Cross Site Scripting attacks on MapServer.
Impacted products: Debian, Fedora, Unix (platform) ~ not comprehensive.
Severity: 3/4.
Consequences: user access/rights.
Provenance: internet client.
Number of vulnerabilities in this bulletin: 2.
Creation date: 05/09/2007.
Identifiers: CVE-2007-4542, CVE-2007-4629, DSA-1539-1, FEDORA-2007-2018, VIGILANCE-VUL-7144.

Description of the vulnerability

The MapServer program handles cartography data. It is affected by two types of vulnerabilities.

Special characters are not encoded by msEncodeHTMLEntities() in the maptemplate.c file. Moreover, the msWriteError() function is incorrectly used in the mapserv.c file. An attacker can use these errors in order to create a Cross Site Scripting attack. [severity:3/4; CVE-2007-4542]

An attacker can create a mapfile with a long layer name, group name or metadata entry name. An overflow then occurs in the processLine() function of maptemplate.c file. This overflow can lead to code execution. [severity:3/4; CVE-2007-4629]

MIT krb5: buffer overflows of kadmind

Synthesis of the vulnerability

An attacker, authenticated or not authenticated, can create two overflows in kadmind in order to execute code.
Impacted products: Debian, Fedora, Mandriva Linux, MIT krb5, NLD, OES, openSUSE, Solaris, Trusted Solaris, RHEL, SLES.
Severity: 3/4.
Consequences: administrator access/rights.
Provenance: intranet client.
Number of vulnerabilities in this bulletin: 2.

Identifiers: 103060, 6591024, BID-25533, BID-25534, CERTA-2002-AVI-162, CERTA-2007-AVI-390, CVE-2007-3999, CVE-2007-4000, CVE-2007-4743, DSA-1367-1, DSA-1367-2, DSA-1368-1, DSA-1387-1, FEDORA-2007-2017, FEDORA-2007-690, FEDORA-2008-1017, MDKSA-2007:174, MDKSA-2007:181, MITKRB5-SA-2007-006, RHSA-2007:0858-01, RHSA-2007:0892-01, RHSA-2007:0913-01, RHSA-2007:0951-01, SUSE-SR:2007:019, SUSE-SR:2007:024, VIGILANCE-VUL-7143, VU#377544, VU#883632, ZDI-07-052.

Description of the vulnerability

Two buffer overflow affect the kadmind daemon of the MIT krb5 implementation.

The svcauth_gss_validate() function of src/lib/rpc/svc_auth_gss.c file incorrectly check size of data before copying them via memcpy(). This function is used during a RPCSEC_GSS authentication. An unauthenticated attacker can therefore generate an overflow in order to execute code on kadmind daemon. Other applications compiled with the RPC library are also potentially vulnerable. [severity:3/4; BID-25534, CERTA-2007-AVI-390, CVE-2007-3999, CVE-2007-4743, VU#883632, ZDI-07-052]

The kadm5_modify_policy_internal() function of src/lib/kadm5/srv/svr_policy.c file does not correctly check if krb5_db_get_policy() function failed, and thus uses an uninitialized pointer. This pointer is then used to alter data, which corrupts memory. An authenticated attacker, with the "modify policy" privilege, can therefore execute code on the kadmind daemon.

vulnerability announce CVE-2007-4732

Solaris: denial of service via strfreectty

Synthesis of the vulnerability

A local attacker can use the strfreectty() function on a SPECFS filesystem in order to generate a denial of service.
Impacted products: Solaris, Trusted Solaris.
Severity: 1/4.
Consequences: denial of service on server.
Provenance: user shell.
Creation date: 03/09/2007.
Identifiers: 103009, 6322179, BID-25510, CVE-2007-4732, VIGILANCE-VUL-7142.

Description of the vulnerability

The SPECFS (Special File System) filesystem is for example used to access to some special files.

The pgsignal() function sends a signal to a group of processes:
  void pgsignal(struct pgrp *pgrp, int signum, int checkctty);

A local attacker can force the strfreectty() function of SPECFS to send a NULL pointer to the pgsignal() function.

A local attacker can therefore panic the system.

vulnerability alert CVE-2007-4460

id3lib: file corruption

Synthesis of the vulnerability

A local attacker can alter a file with rights of applications linked to id3lib.
Impacted products: Debian, Fedora, Mandriva Linux, NLD, OES, openSUSE, Solaris, SLES, Unix (platform) ~ not comprehensive.
Severity: 1/4.
Consequences: data creation/edition.
Provenance: user shell.
Creation date: 03/09/2007.
Identifiers: BID-25372, CERTA-2002-AVI-162, CERTA-2013-AVI-543, CVE-2007-4460, DSA-1365-1, FEDORA-2007-1774, MDKSA-2007:180, SUSE-SR:2007:019, VIGILANCE-VUL-7141.

Description of the vulnerability

The id3lib library handles ID3 audio tags.

The RenderV2ToFile() function of src/tag_file.cpp file creates a temporary file. However, this filename can be predicted because a "#if defined(__GNUC__)" is incorrectly used.

A local attacker can therefore create a symbolic link with this name in order to force creation or corruption of a file with rights of victims who run programs linked with id3lib.
