Description
This security bulletin contains information about 4 secuirty vulnerabilities.
1) Out-of-bounds write (CVE-ID: CVE-2017-14040)
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
An invalid write access was discovered in bin/jp2/convert.c in OpenJPEG 2.2.0, triggering a crash in the tgatoimage function. The vulnerability may lead to remote denial of service or possibly unspecified other impact.
2) Out-of-bounds write (CVE-ID: CVE-2017-14041)
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
A stack-based buffer overflow was discovered in the pgxtoimage function in bin/jp2/convert.c in OpenJPEG 2.2.0. The vulnerability causes an out-of-bounds write, which may lead to remote denial of service or possibly remote code execution.
3) Out-of-bounds write (CVE-ID: CVE-2017-14152)
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
A mishandled zero case was discovered in opj_j2k_set_cinema_parameters in lib/openjp2/j2k.c in OpenJPEG 2.2.0. The vulnerability causes an out-of-bounds write, which may lead to remote denial of service (heap-based buffer overflow affecting opj_write_bytes_LE in lib/openjp2/cio.c and opj_j2k_write_sot in lib/openjp2/j2k.c) or possibly remote code execution.
4) Buffer overflow (CVE-ID: CVE-2017-14151)
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
An off-by-one error was discovered in opj_tcd_code_block_enc_allocate_data in lib/openjp2/tcd.c in OpenJPEG 2.2.0. The vulnerability causes an out-of-bounds write, which may lead to remote denial of service (heap-based buffer overflow affecting opj_mqc_flush in lib/openjp2/mqc.c and opj_t1_encode_cblk in lib/openjp2/t1.c) or possibly remote code execution.
