Who gets CERT's attention
Backers of proprietary software have, at times in the past, resorted to claims that Linux and free software are the subject of more CERT advisories than other systems. Such claims have been strikingly absent recently. Since our detractors have apparently been too busy to tally up CERT's output this year, we've decided to do it for them. Here's the full list of CERT's 2004 "technical cyber security alerts":
| ID | Date | Vulnerability | Linux | Windows | Other |
|---|---|---|---|---|---|
| TA04-028A | Jan 28 | MyDoom.B virus |  |
||
| TA04-033A | Feb. 2 | Multiple Internet Explorer holes | |
||
| TA04-036A | Feb. 5 | Check Point Firewall HTTP parsing | |
||
| TA04-041A | Feb. 10 | Multiple ASN.1 holes | |
||
| TA04-070A | Mar. 10 | Outlook mailto: handling vulnerability | |
||
| TA04-078A | Mar. 19 | Multiple OpenSSL vulnerabilities | |
||
| TA04-099A | Apr. 8 | Outlook Express MHTML cross-domain | |
||
| TA04-104A | Apr. 14 | Multiple vulnerabilities in Microsoft products | |
||
| TA04-111A | Apr. 20 | TCP/BGP session termination | |
|
|
| TA04-111B | Apr. 20 | Cisco IOS SNMP message handling | |
||
| TA04-147A | May 26 | CVS heap overflow | |
||
| TA04-160A | Jun. 9 | Oracle SQL injection | |
||
| TA04-163A | Jun. 11 | Internet Explorer cross-domain redirect | |
||
| TA04-174A | Jun. 22 | Multiple DHCP vulnerabilities | |
||
| TA04-184A | Jul. 2 | Internet Explorer ADOBD.Stream control | |
||
| TA04-196A | Jul. 14 | Multiple Windows/Outlook vulnerabilities | |
||
| TA04-212A | Jul. 30 | "Critical" Windows/IE remote code execution | |
||
| TA04-217A | Aug. 4 | Multiple libpng vulnerabilities | |
||
| TA04-245A | Sep. 1 | Multiple Oracle vulnerabilities | |
||
| TA04-247A | Sep. 3 | MIT Kerberos 5 | |
||
| TA04-260A | Sep. 16 | Microsoft JPEG component | |
||
| TA04-261A | Sep. 17 | Multiple Mozilla vulnerabilities | |
||
| TA04-293A | Nov. 10 | Multiple Internet Explorer vulnerabilities | |
||
| TA04-315A | Nov. 11 | Internet Explorer buffer overflow | |
||
| TA04-316A | Nov. 11 | IOS input queue vulnerability | |
||
| TOTALS: | 7 | 13 | 6 |
Now, one can raise all sorts of complaints about this table. The logic that assigns the Mozilla vulnerability to Linux could also, easily, have charged it to Windows as well. The process by which CERT chooses vulnerabilities worthy of "cyber security alerts" is poorly understood. And so on.
There are seven vulnerabilities in the Linux column - and that is seven too many. But that is far less than the count in the proprietary columns. The Windows vulnerabilities include many which affect a large percentage of users; instead, very few users were affected by most of the Linux problems. The CERT advisory count is a flawed measure at best, but, within its limits, it shows that things could be a lot worse.

libgd2: buffer overflows in PNG handling
| Package(s): | libgd2 | CVE #(s): | CAN-2004-0990 CAN-2004-0941 | |||||||||||||||||||||||||||||||||||||||||||||||||||
| Created: | October 29, 2004 | Updated: | June 28, 2006 | |||||||||||||||||||||||||||||||||||||||||||||||||||
| Description: | Several buffer overflows have been discovered in libgd's PNG handling
functions.
If an attacker tricked a user into loading a malicious PNG image, they could leverage this into executing arbitrary code in the context of the user opening image. Most importantly, this library is commonly used in PHP. One possible target would be a PHP driven photo website that lets users upload images. Therefore this vulnerability might lead to privilege escalation to a web server's privileges. Multiple buffer overflows in the gd graphics library (libgd) 2.0.21 and earlier may allow remote attackers to execute arbitrary code via malformed image files that trigger the overflows due to improper calls to the gdMalloc function. | |||||||||||||||||||||||||||||||||||||||||||||||||||||
