exif.c in PHP before 4.3.11 allows remote attackers to cause a denial of service (memory consumption and crash) via an EXIF header with a large IFD nesting level, which causes significant stack recursion.

scan.c for LibXPM may allow attackers to execute arbitrary code via a negative bitmap_unit value that leads to a buffer overflow.

Multiple vulnerabilities in xli before 1.17 may allow remote attackers to execute arbitrary code via "buffer management errors" from certain image properties, some of which may be related to integer overflows in PPM files.

xloadimage before 4.1-r2, and xli before 1.17, allows attackers to execute arbitrary commands via shell metacharacters in filenames for compressed images, which are not properly quoted when calling the gunzip command.

The EPSF pipe support in enscript 1.6.3 allows remote attackers or local users to execute arbitrary commands via shell metacharacters.

Opera 7.54 and earlier uses kfmclient exec to handle unknown MIME types, which allows remote attackers to execute arbitrary code via a shortcut or launcher that contains an Exec entry.

The Internet Group Management Protocol (IGMP) allows local users to cause a denial of service via an IGMP membership report to a target's Ethernet address instead of the Multicast group address, which causes the target to stop sending reports to the router and effectively disconnect the group from the network.

Buffer overflow in lukemftp FTP client in SuSE 6.4 through 8.0, and possibly other operating systems, allows a malicious FTP server to execute arbitrary code via a long PASV command.

Off-by-one error in the channel code of OpenSSH 2.0 through 3.0.2 allows local users or remote malicious servers to gain privileges.

Heap corruption vulnerability in the "at" program allows local users to execute arbitrary code via a malformed execution time, which causes at to free the same memory twice.
