From: "yanjun.zhu" <yanjun....@windriver.com> Reference:http://http://bugs.python.org/issue14579
The utf-16 decoder in Python 3.1 through 3.3 does not update the aligned_end variable after calling the unicode_decode_call_errorhandler function, which allows remote attackers to obtain sensitive information (process memory) or cause a denial of service (memory corruption and crash) via unspecified vectors. http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2012-2135 Signed-off-by: yanjun.zhu <yanjun....@windriver.com> --- .../python/python/python-2.7.2-CVE-2012-2135.patch | 22 ++++++++++++++++++++++ meta/recipes-devtools/python/python_2.7.2.bb | 1 + 2 files changed, 23 insertions(+) create mode 100644 meta/recipes-devtools/python/python/python-2.7.2-CVE-2012-2135.patch diff --git a/meta/recipes-devtools/python/python/python-2.7.2-CVE-2012-2135.patch b/meta/recipes-devtools/python/python/python-2.7.2-CVE-2012-2135.patch new file mode 100644 index 0000000..bb9719e --- /dev/null +++ b/meta/recipes-devtools/python/python/python-2.7.2-CVE-2012-2135.patch @@ -0,0 +1,22 @@ +Reference:http://http://bugs.python.org/issue14579 + +The utf-16 decoder in Python 3.1 through 3.3 does not update the +aligned_end variable after calling the unicode_decode_call_errorhandler +function, which allows remote attackers to obtain sensitive information +(process memory) or cause a denial of service (memory corruption and crash) +via unspecified vectors. + +http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2012-2135 +Signed-off-by: yanjun.zhu <yanjun....@windriver.com> +diff -urpN a/Objects/unicodeobject.c b/Objects/unicodeobject.c +--- a/Objects/unicodeobject.c 2012-11-12 16:25:33.000000000 +0800 ++++ b/Objects/unicodeobject.c 2012-11-12 16:26:22.000000000 +0800 +@@ -2568,7 +2568,7 @@ PyUnicode_DecodeUTF16Stateful(const char + } + + /* UTF-16 code pair: */ +- if (q >= e) { ++ if (e - q < 2) { + errmsg = "unexpected end of data"; + startinpos = (((const char *)q)-2)-starts; + endinpos = ((const char *)e)-starts; diff --git a/meta/recipes-devtools/python/python_2.7.2.bb b/meta/recipes-devtools/python/python_2.7.2.bb index 2adb4e4..9dabfb7 100644 --- a/meta/recipes-devtools/python/python_2.7.2.bb +++ b/meta/recipes-devtools/python/python_2.7.2.bb @@ -24,6 +24,7 @@ SRC_URI += "\ file://setuptweaks.patch \ file://check-if-target-is-64b-not-host.patch \ file://search_db_h_in_inc_dirs_and_avoid_warning.patch \ + file://python-2.7.2-CVE-2012-2135.patch \ " S = "${WORKDIR}/Python-${PV}" -- 1.7.11 _______________________________________________ Openembedded-core mailing list Openembedded-core@lists.openembedded.org http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/openembedded-core
