Severity: Normal Title: JasPer: User-assisted execution of arbitrary code Date: December 16, 2008 Bugs: #222819 ID: 200812-18

Synopsis ========
Multiple memory management errors in JasPer might lead to execution of arbitrary code via jpeg2k files.
Background ==========
The JasPer Project is an open-source initiative to provide a free software-based reference implementation of the codec specified in the JPEG-2000 Part-1 (jpeg2k) standard.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-libs/jasper < 1.900.1-r3 >= 1.900.1-r3
Description ===========
Marc Espie and Christian Weisgerber have discovered multiple vulnerabilities in JasPer:
* Multiple integer overflows might allow for insufficient memory allocation, leading to heap-based buffer overflows (CVE-2008-3520).
* The jas_stream_printf() function in libjasper/base/jas_stream.c uses vsprintf() to write user-provided data to a static to a buffer, leading to an overflow (CVE-2008-3522).
Impact ======
Remote attackers could entice a user or automated system to process specially crafted jpeg2k files with an application using JasPer, possibly leading to the execution of arbitrary code.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All JasPer users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=media-libs/jasper-1.900.1-r3"
