The wv library is vulnerable to multiple integer overflows which could lead to the execution of arbitrary code.
|Package||app-text/wv on all architectures|
|Affected versions||< 1.2.3-r1|
|Unaffected versions||>= 1.2.3-r1|
wv is a library for conversion of MS Word DOC and RTF files.
The wv library fails to do proper arithmetic checks in multiple places, possibly leading to integer overflows.
An attacker could craft a malicious file that, when handled with the wv library, could lead to the execution of arbitrary code with the permissions of the user running the application.
There is no known workaround at this time.
All wv library users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-text/wv-1.2.3-r1"
