Detail
Multiple buffer overflows in Exim before 4.43 may allow attackers to execute arbitrary code via (1) an IPv6 address with more than 8 components, as demonstrated using the -be command line option, which triggers an overflow in the host_aton function, or (2) the -bh command line option or dnsdb PTR lookup, which triggers an overflow in the dns_build_reverse function. |

Title: | Perl-Compatible Regular Expression (PCRE) library before 7.3 allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via regex patterns containing unmatched "\Q\E" sequences with orphan "\E" codes. | ||

Open Source Vulnerability Database (OSVDB)
Id | Description |
---|---|
12946 | Exim -bh Command Line Option dns_build_reverse Function Local Overflow A local overflow exists in Exim. Exim fails to check the length of a string resulting in a buffer overflow in the dns_build_reverse() function. Exim drops SUID privileges before the vulnerable code is reached. With a specially crafted request, an attacker can further escalate privileges or retrieve the mailer uid to access email messages, resulting in a loss of integrity and confidentiality. |
12726 | Exim -be Command Line Option host_aton Function Local Overflow A remote overflow exists in Exim. Exim fails to properly check input to host_aton() resulting in a buffer overflow. With a specially crafted request of an IPv6 address with more than 8 components, an attacker can cause execution of arbitrary code resulting in a loss of integrity. |
