Static SSP canary in Debian libc6
| CENSUS ID: | CENSUS-2009-0001 |
| Affected Products: | All SSP-armoured applications, statically or dynamically linked against the libc6 library (versions ≤ 2.7) provided by the Debian GNU/Linux project. |
| Class: | Degraded performance of security mechanism due to misconfiguration. |
| Discovered by: | Dimitris Glynos |
We have found that Debian packages of the GNU libc library (versions prior to and including 2.7) provide a static (i.e. guessable) canary value to all applications armoured with the gcc SSP mechanism.
