Synopsis ========
A buffer overflow in GNU Chess might allow arbitrary code execution.
Background ==========
GNU Chess is a console based chess interfae.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 games-board/gnuchess < 6.2.8-r1 >= 6.2.8-r1
Description ===========
The cmd_pgnload() and cmd_pgnreplay() functions in cmd.cc in GNU Chess to not sufficiently validate PGN file input, potentially resulting in a buffer overflow.
Impact ======
A remote attacker could entice a user to open a specially crafted PGN file using GNU Chess, possibly resulting in execution of arbitrary code with the privileges of the process or a Denial of Service condition.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All GNU Chess users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=games-board/gnuchess-6.2.8-r1"
