Description
This security bulletin contains information about 2 vulnerabilities.
1) Buffer overflow (CVE-ID: CVE-2012-3422)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N]
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
The getFirstInTableInstance function in the IcedTea-Web plugin before 1.2.1 returns an uninitialized pointer when the instance_to_id_map hash is empty, which allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted web page, which causes an uninitialized memory location to be read.
2) Buffer overflow (CVE-ID: CVE-2012-3423)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N]
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
The IcedTea-Web plugin before 1.2.1 does not properly handle NPVariant NPStrings without NUL terminators, which allows remote attackers to cause a denial of service (crash), obtain sensitive information from memory, or execute arbitrary code via a crafted Java applet.
