Category:	Debian Local Security Checks
Title:	Debian: Security Advisory (DLA-3682-1)
Summary:	The remote host is missing an update for the Debian 'ncurses' package(s) announced via the DLA-3682-1 advisory.
Description:	Summary: The remote host is missing an update for the Debian 'ncurses' package(s) announced via the DLA-3682-1 advisory. Vulnerability Insight: Issues were found in ncurses, a collection of shared libraries for terminal handling, which could lead to denial of service. CVE-2021-39537 It has been discovered that the tic(1) utility is susceptible to a heap overflow on crafted input due to improper bounds checking. CVE-2023-29491 Jonathan Bar Or, Michael Pearse and Emanuele Cozzi have discovered that when ncurses is used by a setuid application, a local user can trigger security-relevant memory corruption via malformed data in a terminfo database file found in $HOME/.terminfo or reached via the TERMINFO or TERM environment variables. In order to mitigate this issue, ncurses now further restricts programs running with elevated privileges (setuid/setgid programs). Programs run by the superuser remain able to load custom terminfo entries. This change aligns ncurses' behavior in buster-security with that of Debian Bullseye's latest point release (6.2+20201114-2+deb11u2). For Debian 10 buster, these problems have been fixed in version 6.1+20181013-2+deb10u5. We recommend that you upgrade your ncurses packages.

Solution: Please install the updated package(s). CVSS Score: 6.8 CVSS Vector: AV:N/AC:M/Au:N/C:P/I:P/A:P
