Ubuntu priority

Medium

Why this priority?

Off-by-one error in the XML signature feature in Apache XML Security for C++ 1.6.0, as used in Shibboleth before 2.4.3 and possibly other products, allows remote attackers to cause a denial of service (crash) via a signature using a large RSA key, which triggers a buffer overflow.

Notes

sbeattie

shibboleth-sp2 apparently needs to be recompiled after the fix to xml-security-c
