Vulnerability Assessment Details
Crypt::CBC: Insecure initialization vector
Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200603-15
(Crypt::CBC: Insecure initialization vector)
Lincoln Stein discovered that Crypt::CBC fails to handle 16 bytes
long initializiation vectors correctly when running in the RandomIV
mode, resulting in a weaker encryption because the second part of every
block will always be encrypted with zeros if the blocksize of the
cipher is greater than 8 bytes.
A possible hacker could exploit weak ciphertext produced by Crypt::CBC
to bypass certain security restrictions or to gain access to sensitive
There is no known workaround at this time.
All Crypt::CBC users should upgrade to the latest available
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-perl/crypt-cbc-2.17"
Network Security Threat Level: Low
