Package: php5
Severity: grave
Tags: security, patch
Justification: user security hole
Hi,
the following CVE (Common Vulnerabilities & Exposures) id was
published for php5.
CVE-2008-5557[0]:
| Heap-based buffer overflow in
| ext/mbstring/libmbfl/filters/mbfilter_htmlent.c in the mbstring
| extension in PHP 4.3.0 through 5.2.6 allows context-dependent
| attackers to execute arbitrary code via a crafted string containing an
| HTML entity, which is not properly handled during Unicode conversion,
| related to the (1) mb_convert_encoding, (2) mb_check_encoding, (3)
| mb_convert_variables, and (4) mb_parse_str functions.
There are some more information available in the php bugreport[1],
including the PoC which seems to work.
If you fix the vulnerability please also make sure to include the
CVE id in your changelog entry.
Cheers
Steffen
