Mandriva Linux Security Advisory : gnupg2 (MDVSA-2010:143)
Medium Nessus Plugin ID 48209
SynopsisThe remote Mandriva Linux host is missing a security update.
DescriptionA vulnerability has been discovered and corrected in gnupg2 :
Importing a certificate with more than 98 Subject Alternate Names via GPGSM's import command or implicitly while verifying a signature causes GPGSM to reallocate an array with the names. The bug is that the reallocation code misses assigning the reallocated array to the old array variable and thus the old and freed array will be used.
Usually this leads to a segv (CVE-2010-2547).
Packages for 2008.0 and 2009.0 are provided as of the Extended Maintenance Program. Please visit this link to learn more:
The updated packages have been patched to correct this issue.
