Vulnerability Assessment Details
Perl: Format string errors can lead to code execution
Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200512-01
(Perl: Format string errors can lead to code execution)
Jack Louis discovered a new way to exploit format string errors in
Perl that could lead to the execution of arbitrary code. This is
perfomed by causing an integer wrap overflow in the efix variable
inside the function Perl_sv_vcatpvfn. The proposed fix closes that
specific exploitation vector to mitigate the risk of format string
programming errors in Perl. This fix does not remove the need to fix
such errors in Perl code.
Perl applications making improper use of printf functions (or
derived functions) using untrusted data may be vulnerable to the
already-known forms of Perl format string exploits and also to the
execution of arbitrary code.
Fix all misbehaving Perl applications so that they make proper use
of the printf and derived Perl functions.
All Perl users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose dev-lang/perl
Network Security Threat Level: High
