Description
This security bulletin contains information about 5 secuirty vulnerabilities.
1) Out-of-bounds read (CVE-ID: CVE-2020-10177)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in "libImaging/FliDecode.c". A remote attacker can trigger out-of-bounds read error and read contents of memory on the system.
2) Out-of-bounds read (CVE-ID: CVE-2020-10994)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in "libImaging/Jpeg2KDecode.c". A remote attacker can create a specially crafted JP2 file, trick the victim into opening it, trigger out-of-bounds read error and read contents of memory on the system.
3) Buffer overflow (CVE-ID: CVE-2020-10379)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in "libImaging/TiffDecode.c". A remote attacker can trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
4) Out-of-bounds read (CVE-ID: CVE-2020-11538)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition within the parsing of SGI image files in "libImaging/SgiRleDecode.c". A remote attacker can create a specially crafted SGI file, trick the victim into opening it, trigger out-of-bounds read error and read contents of memory on the system.
5) Out-of-bounds read (CVE-ID: CVE-2020-10378)
The vulnerability allows a remote attacker to perform a denial of service attack.
The vulnerability exists due to an out-of-bounds read in "libImaging/PcxDecode.c" that occurs when reading PCX files where state->shuffle is instructed to read beyond state->buffer. A remote attacker can create a specially crafted PCX file, trick the victim into opening it, trigger out-of-bounds read error and read contents of memory on the system.
