Eval injection vulnerability in (1) courier-imapd.indirect and (2) courier-pop3d.indirect in Courier-IMAP before 4.0.6-r2, and 4.1.x before 4.1.2-r1, on Gentoo Linux allows remote attackers to execute arbitrary commands via the XMAILDIR variable, related to the LOGINRUN variable.
Vixie Cron before 4.1-r10 on Gentoo Linux is installed with insecure permissions, which allows local users to cause a denial of service (cron failure) by creating hard links, which results in a failed st_nlink check in database.c.
The gnu regular expression code in file 4.20 allows context-dependent attackers to cause a denial of service (CPU consumption) via a crafted document with a large number of line feed characters, which is not well handled by OS/2 REXX regular expressions that use wildcards, as originally reported for AMaViS.
The Linux Security Auditing Tool (LSAT) allows local users to overwrite arbitrary files via a symlink attack on temporary files, as demonstrated using /tmp/lsat1.lsat.
ftpd, as used by Gentoo and Debian Linux, sets the gid to the effective uid instead of the effective group id before executing /bin/ls, which allows remote authenticated users to list arbitrary directories with the privileges of gid 0 and possibly enable additional attack vectors.
Cross-site scripting (XSS) vulnerability in the wp_explain_nonce function in the nonce AYS functionality (wp-includes/functions.php) for WordPress 2.0 before 2.0.9 and 2.1 before 2.1.1 allows remote attackers to inject arbitrary web script or HTML via the file parameter to wp-admin/templates.php, and possibly other vectors involving the action variable.
The gencert.sh script, when installing OpenLDAP before 2.1.30-r10, 2.2.x before 2.2.28-r7, and 2.3.x before 2.3.30-r2 as an ebuild in Gentoo Linux, does not create temporary directories in /tmp securely during emerge, which allows local users to overwrite arbitrary files via a symlink attack.
The JPEG library in media-libs/jpeg before 6b-r7 on Gentoo Linux is built without the -maxmem feature, which could allow context-dependent attackers to cause a denial of service (memory exhaustion) via a crafted JPEG file that exceeds the intended memory limits.
The configuration of NetHack 3.4.3-r1 and earlier, Falcon's Eye 1.9.4a and earlier, and Slash'EM 0.0.760 and earlier on Gentoo Linux allows local users in the games group to modify saved games files to execute arbitrary code via buffer overflows and overwrite arbitrary files via symlink attacks.
The ebuild for pinentry before 0.7.2-r2 on Gentoo Linux sets setgid bits for pinentry programs, which allows local users to read or overwrite arbitrary files as gid 0.
