debian.nano.txt |
Description:
|
Debian Security Advisory - The problem that was previously reported for joe also occurs with other editors. When nano (a free pico clone) unexpectedly dies it tries a warning message to a new file with a predictable name. Unfortunately that file was not created safely which made nano vulnerable to a symlink attack. This has been fixed in version 0.9.23-1 (except for powerpc, which has version 0.9.23-1.1).

debian.ethereal.txt |
Description:
|
Debian Security Advisory - Hacksware reported a buffer overflow in the AFS packet parsing code in ethereal. Gerald Combs then found more overflows in the netbios and ntp decoding logic as well. An attacker can exploit those overflows by sending carefully crafted packets to a network that is being monitored by ethereal. This has been fixed in version 0.8.0-2potato and we recommend you upgrade your ethereal package immediately.

Description:

Debian Security Advisory - When joe (Joe's Own Editor) dies due to a signal instead of a normal exit it saves a list of the files it is editing to a file called DEADJOE in its current directory. Unfortunately this wasn't done safely which made joe vulnerable to a symlink attack.

debian.ghostscript.txt |
Description:
|
Debian Security Advisory - ghostscript uses temporary files to do some of its work. Unfortunately the method used to create those files wasn't secure: mktemp was used to create a name for a temporary file, but the file was not opened safely. A second problem is that during build the LD_RUN_PATH environment variable was set to the empty string, which causes the dynamic linker to look in the current directory for shared libraries.

debian.ncurses.txt |
Description:
|
Debian Security Advisory - The version of the ncurses display library shipped with Debian GNU/Linux 2.2 is vulnerable to several buffer overflows in the parsing of terminfo database files. The problems are only exploitable in the presence of setuid binaries linked to ncurses which use these particular functions, including xmcd versions before 2.5pl1-7.1.

debian.xcmd.txt |
Description:
|
Debian Security Advisory - The Debian GNU/Linux xmcd package has historically installed two setuid helpers for accessing cddb databases and SCSI cdrom drives. More recently, the package offered the administrator the chance to remove these setuid flags, but did so incorrectly. A buffer overflow in ncurses, linked to the "cda" binary, allowed a root exploit. Fixed ncurses packages have been released, as well as fixed xmcd packages which do not install this binary with a setuid flag. The problem is fixed in xmcd 2.5pl1-7.1, and we recommend all users with xmcd installed upgrade to this release. You may need to add users of xmcd to the "audio" and "cdrom" groups in order for them to continue using xmcd.

debian.cron.txt |
Description:
|
Debian Security Advisory - The version of Vixie Cron shipped with Debian GNU/Linux 2.2 is vulnerable to a local attack, discovered by Michal Zalewski. Several problems, including insecure permissions on temporary files and race conditions in their deletion, allowed attacks from a denial of service (preventing the editing of crontabs) to an escalation of privilege (when another user edited their crontab). As a temporary fix, "chmod go-rx /var/spool/cron/crontabs" prevents the only available exploit; however, it does not address the problem - upgrade is needed.

This could be exploited by the remote machine by returning an invalid response to a request from curl which overflows the error buffer and trick curl into executing arbitrary code.
