libextractor is affected by several overflow vulnerabilities in the PDF, Real and PNG extractors, making it vulnerable to execution of arbitrary code.
|Package||media-libs/libextractor on all architectures|
|Affected versions||< 0.5.0|
|Unaffected versions||>= 0.5.0|
libextractor is a library used to extract meta-data from files. It makes use of Xpdf code to extract information from PDF files.
Xpdf is vulnerable to multiple overflows, as described in GLSA 200501-28. Also, integer overflows were discovered in Real and PNG extractors.
An attacker could design malicious PDF, PNG or Real files which, when processed by an application making use of libextractor, would result in the execution of arbitrary code with the rights of the user running the application.
There is no known workaround at this time.
All libextractor users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=media-libs/libextractor-0.5.0"
