GLSA-200506-06 : libextractor: Multiple overflow vulnerabilities
High Nessus Plugin ID 18448
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200506-06 (libextractor: Multiple overflow vulnerabilities)
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.
SolutionAll libextractor users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=media-libs/libextractor-0.5.0'
