Description

This security bulletin contains information about 2 secuirty vulnerabilities.


1) Format string error (CVE-ID: CVE-2010-2094)

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

Multiple format string vulnerabilities in the phar extension in PHP 5.3 before 5.3.2 allow context-dependent attackers to obtain sensitive information (memory contents) and possibly execute arbitrary code via a crafted phar:// URI that is not properly handled by the (1) phar_stream_flush, (2) phar_wrapper_unlink, (3) phar_parse_url, or (4) phar_wrapper_open_url functions in ext/phar/stream.c; and the (5) phar_wrapper_open_dir function in ext/phar/dirstream.c, which triggers errors in the php_stream_wrapper_log_error function.


2) Input validation error (CVE-ID: CVE-2010-0397)

The vulnerability allows context-dependent attackers to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can cause a denial of service (NULL pointer dereference and application crash) and possibly have unspecified other impact via a crafted argument.
