Language:

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-202107-28 (GNU Chess: Buffer overflow)

 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.

Solution

All GNU Chess users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=games-board/gnuchess-6.2.8-r1'
