GLSA-200606-25 : Hashcash: Possible heap overflow
High Nessus Plugin ID 21758
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200606-25 (Hashcash: Possible heap overflow)
Andreas Seltenreich has reported a possible heap overflow in the array_push() function in hashcash.c, as a result of an incorrect amount of allocated memory for the 'ARRAY' structure.
By sending malicious entries to the Hashcash utility, an attacker may be able to cause an overflow, potentially resulting in the execution of arbitrary code with the privileges of the user running the application.
There is no known workaround at this time.
SolutionAll Hashcash users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-misc/hashcash-1.21'
