The zziplib library contains a buffer overflow vulnerability that could lead to user-assisted remote execution of arbitrary code.
|Package||dev-libs/zziplib on all architectures|
|Affected versions||< 0.13.49|
|Unaffected versions||>= 0.13.49|
The zziplib library is a lightweight library for extracting data from files archived in a single zip file.
dmcox dmcox discovered a boundary error in the zzip_open_shared_io() function from zzip/file.c .
A remote attacker could entice a user to run a zziplib function with an overly long string as an argument which would trigger the buffer overflow and may lead to the execution of arbitrary code.
There is no known workaround at this time.
All zziplib users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=dev-libs/zziplib-0.13.49"
