Description
This security bulletin contains information about 11 secuirty vulnerabilities.
1) Heap-based buffer overflow (CVE-ID: CVE-2019-15142)
The vulnerability allows a remote attacker to perform denial of service attack.
The vulnerability exists due to a boundary error when processing DJVU files in DjVmDir.cpp in DjVuLibre. A remote attacker can create a specially crafted DJVU, trick the victim into opening it, trigger heap-based buffer overflow and crash the application using the affected library.
2) Infinite loop (CVE-ID: CVE-2019-15143)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop in bitmap reader component in DjVuLibre, related to libdjvu/DjVmDir.cpp and libdjvu/GBitmap.cpp files. A remote attacker can create a specially crafted file, pass it to the application using the affected library and perform denial of service conditions.
3) Infinite loop (CVE-ID: CVE-2019-15144)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop in the sorting functionality (aka GArrayTemplate::sort) within the libdjvu/GContainer.h in DjVuLibre. A remote attacker can consume excessive system resources with a specially crafted BMP file.
4) Out-of-bounds read (CVE-ID: CVE-2019-15145)
The vulnerability allows a remote attacker to perform denial of service (DoS) attack.
The vulnerability exists due to a boundary condition in the JB2Dict::JB2Codec::get_direct_context in libdjvu/JB2Image.h within DjVuLibre due to a missing zero-bytes check in libdjvu/GBitmap.h. A remote attacker can create a specially crafted JB2 file, trick the victim into opening it, trigger out-of-bounds read error and crash the application.
5) NULL pointer dereference (CVE-ID: CVE-2019-18804)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error in the function DJVU::filter_fv at IW44EncodeCodec.cpp. A remote attacker can perform a denial of service (DoS) attack.
6) Stack-based buffer overflow (CVE-ID: CVE-2021-3500)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in DJVU::DjVuDocument::get_djvu_file() function. A remote unauthenticated attacker can create a specially crafted djvu file, trick the victim into opening it, trigger stack-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
7) Out-of-bounds write (CVE-ID: CVE-2021-3630)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing untrusted input within the DJVU::DjVuTXT::decode() function in DjVuText.cpp. A remote attacker can create a specially crafted djvu file, trick the victim into opening it using the affected software, trigger out-of-bounds write and execute arbitrary code on the target system.
8) Out-of-bounds write (CVE-ID: CVE-2021-32490)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing untrusted input within the DJVU::filter_bv() function. A remote attacker can create a specially crafted djvu file, trick the victim into opening it using the affected software, trigger out-of-bounds write and execute arbitrary code on the target system.
9) Integer overflow (CVE-ID: CVE-2021-32491)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow within render() function in tools/ddjvu. A remote attacker can create a specially crafted djvu file, trick the victim into opening it, trigger integer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
10) Out-of-bounds read (CVE-ID: CVE-2021-32492)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in DJVU::DataPool::has_data() function. A remote attacker can create a specially crafted djvu file, trick the victim into opening it, trigger out-of-bounds read error and read contents of memory on the system.
11) Heap-based buffer overflow (CVE-ID: CVE-2021-32493)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the DJVU::GBitmap::decode() function. A remote attacker can create a specially crafted djvu file, trick the victim into opening it, trigger heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
