Synopsis ========
libwmf is vulnerable to an integer overflow potentially resulting in the execution of arbitrary code.
Background ==========
libwmf is a library for reading and converting vector images in Microsoft's native Windows Metafile Format (WMF).
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-libs/libwmf < 0.2.8.4 >= 0.2.8.4
Description ===========
infamous41md discovered that libwmf fails to do proper bounds checking on the MaxRecordSize variable in the WMF file header. This could lead to an head-based buffer overflow.
Impact ======
By enticing a user to open a specially crafted WMF file, a remote attacker could cause a heap-based buffer overflow and execute arbitrary code with the permissions of the user running the application that uses libwmf.
Workaround ==========
There is no known workaround for this issue.
Resolution ==========
All libwmf users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=media-libs/libwmf-0.2.8.4"
