Local attackers can conduct a denial of service in Midnight Commander 4.x with a symlink attack.

FTP client in Midnight Commander (mc) before 4.5.11 stores usernames and passwords for visited sites in plaintext in the world-readable history file, which allows other local users to gain privileges.

cons.saver in Midnight Commander (mc) 4.5.42 and earlier does not properly verify if an output file descriptor is a TTY, which allows local users to corrupt files by creating a symbolic link to the target file, calling mc, and specifying that link as a TTY argument.

Midnight Commander (mc) 4.5.51 and earlier does not properly process malformed directory names when a user opens a directory, which allows other local users to gain privileges by creating directories that contain special characters followed by the commands to be executed.

Buffer overflow in mcedit in Midnight Commander 4.5.1 allows local users to cause a denial of service (segmentation fault) and possibly execute arbitrary code via a crafted text file.

security flaw

Stack-based buffer overflow in vfs_s_resolve_symlink of vfs/direntry.c for Midnight Commander (mc) 4.6.0 and earlier, and possibly later versions, allows remote attackers to execute arbitrary code during symlink conversion.

security flaw

Multiple buffer overflows in Midnight Commander (mc) before 4.6.0 may allow attackers to cause a denial of service or execute arbitrary code.

security flaw

Multiple vulnerabilities in Midnight Commander (mc) before 4.6.0, with unknown impact, related to "Insecure temporary file and directory creations."

security flaw

Multiple format string vulnerabilities in Midnight Commander (mc) before 4.6.0 may allow attackers to cause a denial of service or execute arbitrary code.

security flaw

Multiple format string vulnerabilities in Midnight Commander (mc) 4.5.55 and earlier allow remote attackers to have an unknown impact.

security flaw

Multiple buffer overflows in Midnight Commander (mc) 4.5.55 and earlier allow remote attackers to have an unknown impact.

security flaw

Midnight commander (mc) 4.5.55 and earlier allows remote attackers to cause a denial of service (infinite loop) via unknown attack vectors.

security flaw

Midnight commander (mc) 4.5.55 and earlier allows remote attackers to cause a denial of service via "a corrupt section header."

security flaw

Midnight commander (mc) 4.5.55 and earlier allows remote attackers to cause a denial of service by triggering a null dereference.

Midnight commander (mc) 4.5.55 and earlier allows remote attackers to cause a denial of service by causing mc to free unallocated memory.

security flaw

Midnight commander (mc) 4.5.55 and earlier allows remote attackers to cause a denial of service via "use of already freed memory."

security flaw

direntry.c in Midnight Commander (mc) 4.5.55 and earlier allows attackers to cause a denial of service by "manipulating non-existing file handles."

security flaw

fish.c in midnight commander allows remote attackers to execute arbitrary programs via "insecure filename quoting," possibly using shell metacharacters.

security flaw

Buffer underflow in extfs.c in Midnight Commander (mc) 4.5.55 and earlier allows remote attackers to cause a denial of service and possibly execute arbitrary code.

security flaw

Buffer overflow in Midnight Commander (mc) 4.5.55 and earlier may allow attackers to execute arbitrary code.
