Description Tomas Hoger 2008-07-18 09:56:25 UTC
oCERT reported a libxslt vulnerability discovered by Chris Evans of the Google
Security Team:

The libexslt library bundled with libxslt is affected by a heap-based buffer
overflow which can lead to arbitrary code execution.

The vulnerability is present in the rc4 encryption/decryption functions. An
arbitrary length string, passed as an argument in the XSL input, is incorrectly
copied over a padding variable which is previously allocated with a fixed size
of 128bit (RC4_KEY_LENGTH).

Affected version: libxslt >= 1.1.8, <= 1.1.24

Acknowledgements:

Red Hat would like to thank Chris Evans and oCERT for reporting this vulnerability.
