Page 4 / 7
6.8 CVSS

Integer overflow in Firebird 2.0.0 allows remote authenticated users to cause a denial of service (CPU consumption) via certain database operations with multi-byte character sets that trigger an attempt to use the value 65536 for a 16-bit integer, which is treated as 0 and causes an infinite loop on zero-length data.

EPSS: 1.32%
4.9 CVSS

fb_lock_mgr in Firebird 1.5 uses weak permissions (0666) for the semaphore array, which allows local users to cause a denial of service (blocked query processing) by locking semaphores.

EPSS: 0.04%
5.5 CVSS

Firebird 1.5 allows remote authenticated users without SYSDBA and owner permissions to overwrite a database by creating a database.

EPSS: 0.20%
7.8 CVSS

Multiple unspecified vulnerabilities in Firebird 1.5 allow remote attackers to (1) cause a denial of service (application crash) by sending many remote protocol versions; and (2) cause a denial of service (connection drop) via certain network traffic, as demonstrated by Nessus vulnerability scanning.

EPSS: 0.80%
6.8 CVSS

Multiple buffer overflows in Firebird 1.5, one of which affects WNET, have unknown impact and attack vectors. NOTE: this issue might overlap CVE-2006-1240.

EPSS: 0.49%
10.0 CVSS
CVE-2007-3181
RCE Exploit Found

Buffer overflow in fbserver.exe in Firebird SQL 2 before 2.0.1 allows remote attackers to execute arbitrary code via a large p_cnct_count value in a p_cnct structure in a connect (0x01) request to port 3050/tcp, related to "an InterBase version of gds32.dll."

EPSS: 29.68%
7.8 CVSS

Multiple buffer overflows in Firebird 2.1 allow attackers to trigger memory corruption and possibly have other unspecified impact via certain input processed by (1) config\ConfigFile.cpp or (2) msgs\check_msgs.epp. NOTE: if ConfigFile.cpp reads a configuration file with restrictive permissions, then the ConfigFile.cpp vector may not cross privilege boundaries and perhaps should not be included in CVE.

EPSS: 0.84%
4.6 CVSS
CVE-2006-1240
Exploit Found

Buffer overflow in inet_server.cpp in (1) fb_inet_server and (2) fbserver in Firebird 1.5.2.4731 allows local users to gain privileges via a long value of the -p argument.

EPSS: 0.33%
4.6 CVSS

Firebird 1.5.2.4731 installs (1) fb_lock_mgr, (2) gds_drop, and (3) fb_inet_server with setuid firebird permissions, which might allow local users to gain privileges via a buffer overflow as identified by CVE-2006-1240, or possibly other vulnerabilities.

EPSS: 0.05%
2.6 CVSS

Mozilla before 1.7, Firefox before 0.9, and Thunderbird before 0.7 allows remote attackers to determine the location of files on a user's hard drive by obscuring a file upload control and tricking the user into dragging text into that control.

EPSS: 0.35%
