Vulnerabilidades

libcaca is a colour ASCII art library. In 0.99.beta20 and earlier, an integer overflow vulnerability in libcaca's canvas import functionality allows an attacker to cause a controlled heap out-of-bounds write (heap overflow) by supplying a crafted file in the "caca" format. Depending on the build configuration and…

libcaca is affected by a Divide By Zero issue via img2txt, which allows a remote malicious user to cause a Denial of Service

A flaw was found in libcaca. A buffer overflow of export.c in function export_troff might lead to memory corruption and other potential consequences.

A flaw was found in libcaca. A heap buffer overflow in export.c in function export_tga might lead to memory corruption and other potential consequences.

A flaw was found in libcaca v0.99.beta19. A buffer overflow issue in caca_resize function in libcaca/caca/canvas.c may lead to local execution of arbitrary code in the user context.

There is an illegal WRITE memory access at caca/file.c (function caca_file_read) in libcaca 0.99.beta19.

There is an illegal WRITE memory access at common-image.c (function load_image) in libcaca 0.99.beta19 for 1bpp data.

There is an illegal READ memory access at caca/dither.c (function get_rgba_default) in libcaca 0.99.beta19 for 24bpp data.

There is an illegal READ memory access at caca/dither.c (function get_rgba_default) in libcaca 0.99.beta19 for the default bpp case.

There is an illegal WRITE memory access at common-image.c (function load_image) in libcaca 0.99.beta19 for 4bpp data.

There is floating point exception at caca/dither.c (function caca_dither_bitmap) in libcaca 0.99.beta19.

Memory leak in the vcard_apdu_new function in card_7816.c in libcacard before 2.5.3 allows local guest OS users to cause a denial of service (host memory consumption) via vectors related to allocating a new APDU object.
