Buffer Overflow vulnerability in jfif_decode() function in rockcarry ffjpeg through version 1.0.0, allows local attackers to execute arbitrary code due to an issue with ALIGN.

In ffjpeg (commit hash: caade60), the function bmp_load() in bmp.c contains an integer overflow vulnerability, which eventually results in the heap overflow in jfif_encode() in jfif.c. This is due to the incomplete patch for issue 38

The function bitstr_tell at bitstr.c in ffjpeg commit 4ab404e has a NULL pointer dereference.

A Null Pointer Dereference vulnerability exits in ffjpeg d5cfd49 (2021-12-06) in bmp_load(). When the size information in metadata of the bmp is out of range, it returns without assign memory buffer to `pb->pdata` and did not exit the program. So the program crashes when it tries to access the pb->data, in jfif_encode() at jfif.c:763. This is due to the incomplete patch for CVE-2020-13438.

Global buffer overflow vulnerability exist in ffjpeg through 01.01.2021. It is similar to CVE-2020-23705. Issue is in the jfif_encode function at ffjpeg/src/jfif.c (line 708) could cause a Denial of Service by using a crafted jpeg file.

Two Heap based buffer overflow vulnerabilities exist in ffjpeg through 01.01.2021. It is similar to CVE-2020-23852. Issues that are in the jfif_decode function at ffjpeg/src/jfif.c (line 552) could cause a Denial of Service by using a crafted jpeg file.

A global buffer overflow vulnerability in jfif_encode at jfif.c:701 of ffjpeg through 2020-06-22 allows attackers to cause a Denial of Service (DOS) via a crafted jpeg file.

A heap based buffer overflow vulnerability exists in ffjpeg through 2020-07-02 in the jfif_decode(void *ctxt, BMP *pb) function at ffjpeg/src/jfif.c (line 544 & line 545), which could cause a denial of service by submitting a malicious jpeg image.

A stack-based buffer overflow vulnerability exists in ffjpeg through 2020-07-02 in the jfif_decode(void *ctxt, BMP *pb) function at ffjpeg/src/jfif.c:513:28, which could cause a denial of service by submitting a malicious jpeg image.
