Package        : gv
Vulnerability  : buffer overflow
Problem-Type   : local(remote)
Debian-specific: no
CVE ID         : CVE-2006-5864
Debian Bug     : 398292

The original update provided in DSA 1214-1 was insufficient; this update corrects this. For reference the original advisory below:

Renaud Lifchitz discovered that gv, the PostScript and PDF viewer for X, performs insufficient boundary checks in the Postscript
parsing code, which allows the execution of arbitrary code through a buffer overflow.

For the stable distribution (sarge) this problem has been fixed in version 3.6.1-10sarge2.

For the upcoming stable distribution (etch) this problem has been fixed in version 3.6.2-2.

For the unstable distribution (sid) this problem has been fixed in version 3.6.2-2.

We recommend that you upgrade your gv package.

Package        : squirrelmail
Vulnerability  : cross-site scripting
Problem-Type   : remote
Debian-specific: no
CVE IDs        : CVE-2006-6142

Martijn Brinkers discovered cross-site scripting vulnerabilities in the the mailto parameter of webmail.php, the session and
delete_draft parameters of compose.php and through a shortcoming in the magicHTML filter. An attacker could abuse these to execute
malicious JavaScript in the user's webmail session. 

Also, a workaround was made for Internet Explorer <= 5: IE will attempt to guess the MIME type of attachments based on content, not
the MIME header sent. Attachments could fake to be an 'harmless' JPEG, while they were in fact HTML that Internet Explorer would
render.

For the stable distribution (sarge) these problems have been fixed in version 2:1.4.4-10.

For the upcoming stable distribution (etch) these problems have been fixed in version 2:1.4.9a-1.

For the unstable distribution (sid) these problems have been fixed in version 2:1.4.9a-1.

We recommend that you upgrade your squirrelmail package.

Package        : elog
Vulnerability  : several
Problem-Type   : remote
Debian-specific: no
CVE ID         : CVE-2006-5063 CVE-2006-5790 CVE-2006-5791 CVE-2006-6318

Several remote vulnerabilities have been discovered in elog, a web-based 
electronic logbook, which may lead to the execution of arbitrary code.
The Common Vulnerabilities and Exposures project identifies the following
problems:

CVE-2006-5063

    Tilman Koschnick discovered that log entry editing in HTML is vulnerable
    to cross-site scripting. This update disables the vulnerable code.

CVE-2006-5790

    Ulf Harnhammar of the Debian Security Audit Project discovered several
    format string vulnerabilities in elog, which may lead to execution of
    arbitrary code.

CVE-2006-5791

    Ulf Harnhammar of the Debian Security Audit Project discovered 
    cross-site scripting vulnerabilities in the creation of new logbook
    entries.

CVE-2006-6318

    Jayesh KS and Arun Kethipelly of OS2A discovered that elog performs
    insufficient error handling in config file parsing, which may lead to
    denial of service through a NULL pointer dereference.

For the stable distribution (sarge) these problems have been fixed in version 2.5.7+r1558-4+sarge3.

The upcoming stable distribution (etch) will no longer include elog.

For the unstable distribution (sid) these problems have been fixed in version 2.6.2+r1754-1.

We recommend that you upgrade your elog package.
