Description:
Chris Evans has reported some vulnerabilities in libxslt, which can be exploited by malicious people to cause a DoS (Denial of Service) and potentially compromise an application using the library.
The vulnerabilities are caused due to boundary errors within crypto.c when handling the XSLT "crypto:rc4_encrypt" and "crypto:rc4_decrypt" functions. This can be exploited to cause a heap-based buffer overflow via a specially crafted stylesheet.
The vulnerability is reported in version 1.1.24. Other versions may also be affected.
Solution:
Fixed in the SVN repository.
Provided and/or discovered by:
Chris Evans, Google Security Team
