CVE-2022-25308

A stack-based buffer overflow flaw was found in the Fribidi package. This flaw allows an attacker to pass a specially crafted file to the Fribidi application, which leads to a possible memory leak or a denial of service.

A stack-based buffer overflow flaw was found in the Fribidi package. This flaw allows an attacker to pass a specially crafted file to the Fribidi application, which leads to a possible memory leak or a denial of service.

A library to handle bidirectional scripts (for example Hebrew, Arabic), so that the display is done in the proper way; while the text data itself is always written in logical order and display in a different direction .

Security Fix(es):

A stack-based buffer overflow flaw was found in the Fribidi package. This flaw allows an attacker to pass a specially crafted file to the Fribidi application, which leads to a possible memory leak or a denial of service.(CVE-2022-25308)

A heap-based buffer overflow flaw was found in the Fribidi package and affects the fribidi_cap_rtl_to_unicode() function of the fribidi-char-sets-cap-rtl.c file. This flaw allows an attacker to pass a specially crafted file to the Fribidi application with the '--caprtl' option, leading to a crash and causing a denial of service.(CVE-2022-25309)

A segmentation fault (SEGV) flaw was found in the Fribidi package and affects the fribidi_remove_bidi_marks() function of the lib/fribidi.c file. This flaw allows an attacker to pass a specially crafted file to Fribidi, leading to a crash and causing a denial of service.(CVE-2022-25310)

It was discovered that FriBidi incorrectly handled processing of input strings resulting in memory corruption. An attacker could use this issue to cause FriBidi to crash, resulting in a denial of service, or potentially execute arbitrary code. (CVE-2022-25308)

It was discovered that FriBidi incorrectly validated input data to its CapRTL unicode encoder, resulting in memory corruption. An attacker could use this issue to cause FriBidi to crash, resulting in a denial of service, or potentially execute arbitrary code. (CVE-2022-25309)

It was discovered that FriBidi incorrectly handled empty input when removing marks from unicode strings, resulting in a crash. An attacker could use this to cause FriBidi to crash, resulting in a denial of service, or potentially execute arbitrary code. (CVE-2022-25310)
