DSA-1026-1 sash -- buffer overflows

Related Vulnerabilities: CVE-2005-1849   CVE-2005-2096  

Markus Oberhumer discovered a flaw in the way zlib, a library used for file compression and decompression, handles invalid input. This flaw can cause programs which use zlib to crash when opening an invalid file. A further error in the way zlib handles the inflation of certain compressed files can cause a program which uses zlib to crash when opening an invalid file. sash, the stand-alone shell, links statically against zlib, and was thus affected by these problems. The old stable distribution (woody) isn't affected by these problems. For the stable distribution (sarge) these problems have been fixed in version 3.7-5sarge1. For the unstable distribution (sid) these problems have been fixed in version 3.7-6. We recommend that you upgrade your sash package.
