If problems still persist, please make note of it in this bug report. libpng10-1.0.41-1.fc8 has been pushed to the Fedora 8 stable repository. If problems still persist, please make note of it in this bug report. I believe all currently-supported releases have fixes for this (libpng10 and libpng) in the stable updates repos now.

Common Vulnerabilities and Exposures assigned an identifier CVE-2008-6218 to the following vulnerability: Memory leak in the png_handle_tEXt function in pngrutil.c in libpng before 1.2.33 rc02 and 1.4.0 beta36 allows context-dependent attackers to cause a denial of service (memory exhaustion) via a crafted PNG file.

None of the applications that use this library are at any risk of causing a denial-of-service in a meaningful way. Client applications are required to reload a bad image multiple times in order to trigger this flaw, we do not consider a crash of a user application to be a security flaw. None of the services that use libpng do so in a long running manner. Our investigation showed that services tend to fork off short lived children to handle these functions, which would not affect the parent process if there was indeed a memory leak. Statement: We do not consider a crash of a client application linked to libpng to be a security issue. None of the applications that use libpng are at any risk of causing a denial of service in a meaningful way. |
