Debian Security Advisories

DSA-3501 perl – security update

Stephane Chazelas discovered a bug in the environment handling in Perl.
Perl provides a Perl-space hash variable, %ENV, in which environment
variables can be looked up. If a variable appears twice in envp, only
the last value would appear in %ENV, but getenv would return the first.
Perl’s taint security mechanism would be applied to the value in %ENV,
but not to the other rest of the environment. This could result in an
ambiguous environment causing environment variables to be propagated to
subprocesses, despite the protections supposedly offered by taint
checking.

DSA-3494 cacti – security update

Two SQL injection vulnerabilities were discovered in cacti, a web
interface for graphing of monitoring systems. Specially crafted input
can be used by an attacker in parameters of the graphs_new.php script to
execute arbitrary SQL commands on the database.

DSA-3493 xerces-c – security update

Gustavo Grieco discovered that xerces-c, a validating XML parser library
for C++, mishandles certain kinds of malformed input documents,
resulting in buffer overflows during processing and error reporting.
These flaws could lead to a denial of service in applications using the
xerces-c library, or potentially, to the execution of arbitrary code.
