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

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.

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